　　In the growth of synthetic mica single crystals, large crystals of synthetic fluorophlogopite have been grown by both endothermic method and seed method, with a maximum area of 506 cm 2, which is the largest synthetic mica sheet in the world so far. The structure of synthetic mica is similar to that of natural mica, and the space group is C. Because synthetic mica does not contain structural water, its temperature is far higher than that of natural mica, reaching 1100 C. It is an excellent insulating rafter material with high temperature resistance. It has a wide range of common uses.

　　Some special applications have been found in recent years, besides being used as electronic tube brackets, capacitors and heat-resistant insulating rafters. Such as high reliable electron tube, long life water level gauge, thermocouple insulator skeleton of resistance surface, window materials such as microwave transmission, X-ray, nuclear radiation, night vision display screen, electron probe, X-ray fluorescence spectrometer and spectrocrystal material, long-wave neutron monochromator, and new adsorbent for purifying radioactive wastewater.

　　In the synthetic mica industrial system based on the internal thermal synthesis of mica, in addition to obtaining a small number of single wafers, there are a large number of broken mica used to produce a variety of synthetic mica composite materials. The main games include synthetic mica powder, synthetic mica ceramics, edible mica paper and its products.

　　2. Synthetic mica powder: Mica powder of various sizes can be obtained by grinding and grading with micro-separator. It is widely used as filler for heat insulation materials, fire-proof coatings, thousand-type fire extinguisher powder, paint, rubber and plastics. In recent years, pearlescent pigments, mica reinforced plastics, heat-resistant enamel, metal high-temperature oxidation-proof coatings, ultra-low hydrogen welding rods and high-temperature lapping and stopping have been developed. Special synthetic mica powder such as welding.

　　Synthetic mica ceramics: Phosphate bonding, glass bonding, melt-casting mica and other ceramic materials are produced by using mica powder. It can be formed by hot pressing, injection or pouring. Its common characteristic is that it has good performance of high temperature absolute rafter, resistance to rapid cold and heat, and can be used for turning, grinding, planer, milling, drilling and other machine mouth worker by ordinary lathe and cutter in wells, with precise size. High finish, widely used in electrical appliances, electrothermal, instrumentation, high-energy ion accelerator and ion nitriding furnace rafters, etc.

　　Synthetic mica paper and its products: Mica crystal block by internal heat method is made into thin sheets by hydraulic braking, and synthetic mica paper is made by papermaking process, then hot-pressed into various plates and rods with inorganic binder. It has a temperature resistance of more than 800oC. It is widely used in electrical appliances, light industry and commercial electric heating equipment. Household appliances made of synthetic mica have the advantages of energy saving and long service life. Synthetic mica electric iron is exported to more than 40 countries and regions in Southeast Asia.

Synthetic Mica and Its Comprehensive Utilization最先出現(xiàn)在友佳云母。

　　1. Oil well drilling mud additives act as sealants.

　　2. In roofing materials, it plays the role of rain proof, heat preservation, heat insulation and decoration.

　　3. Mica powder is used for mineral wool resin and paint mixing. It can be used as decorative coating for concrete, stone and brick through the outer wall.

　　4. Mica powder is used as maintenance coating for welding rods, wires and cables.

　　5. Mica powder is used as filler for oil consumption, pipeline mortar and cementing agent to make decorative coatings, sound-absorbing mortar, ceiling and concrete filler and cement mortar filler to improve the strength of cement mortar.

　　6. Rubber products are used as lubricants and fillers for high-strength electrical insulation and heat-resistant, acid-alkali-resistant products; tires are used as covering agents when they are renovated; and tires are used as lubricants between inner and outer tires in tire manufacturing. In the use of rubber and plastics, the mechanical strength, toughness, adhesion, aging resistance and corrosion resistance of rubber and plastics can be improved.

　　7. In coatings, it can greatly improve the weatherability, water permeability, adhesion between coatings and substrates and strength of coatings, and improve the appearance of coatings.

Application of wet mica powder最先出現(xiàn)在友佳云母。

　　The morphology of dry and wet mica powders differs greatly. Several simple methods for identifying dry and wet mica powders are introduced based on their morphological differences.

　　1. Settlement method: take 10 ml measuring cylinder, add 1 g mica powder, add water 5 ml, shake well, add water to 10 ml scale, shake well. The settlement velocity is observed at rest. Dry mica powder usually settles to the bottom in about 60 minutes, forming about 7 ml of upper clear night. On the contrary, wet mica powder usually forms only about 1.5-3 ml upper layer of clear night, which takes several hours to form about 7 ml upper layer of clear night. The principle is that the wafer of wet mica powder is very thin and has good suspension, while the wafer of dry mica powder is thick and contains more quartz powder, which has poor suspension.

　　2. Density method: The principle is that the wafer of wet mica powder is very thin, and it is difficult to form compact accumulation.

　　A. Loose density method: the powder is fully dispersed, poured into the weighing barrel to a certain scale, weighed and calculated density. The bulk density of wet mica powder is usually about 0.25g/ml, while that of dry mica powder is usually 0.5g/ml.

　　B. Real density method: pour the powder into the weighing barrel, weigh and vibrate (such as tapping lightly on the table) so as to reduce the powder volume until the powder volume no longer drops (usually about 10-15 minutes). Calculate density. The real density of wet mica powder is usually about 0.50g/ml, and that of dry mica powder is between 0.70 and 0.80g/ml.

　　3. Pearlescent effect: take about 0.1-0.2g powder, put it in colorless transparent glass, add water about 60-80ml, stir. The pearlescent effect of wet mica powder is obvious, but that of dry mica powder is poor.

　　In cosmetics, how to make the face shiny? One is to add some oil, but may affect the skin feeling, the product feels greasy after use. Another is to add mica to skin care products and make-up products.

　　Why mica can shine? Here’s a little bit about it.

　　The first is the flaky structure of mica: mica is a rock-forming mineral. Mica used in cosmetics usually has a flaky structure, as shown in the figure. If the sheet structure can cover the pitted skin surface with a layer, the light can form a mirror reflection, rather than a diffuse reflection without a fixed direction, so that the light reflected by the mirror can shine.

　　Secondly, the light irradiated on the mica has a high reflection and a small transmittance so that the light does not pass through the mica (not like glass), but reflects on the surface of the mica.

　　The above two characteristics of mica are summarized as follows:

　　Shine’s definition itself is a comparison between specular reflection and diffuse reflection. If the light passes through the material, or is diffused, it will not be able to form a mirror reflection, forming a gloss.

　　The characteristics and structure of mica can form reflection rather than transmission. On the other hand, the sheet structure determines the mirror reflection that mica can perform (imagine the numerous small mica mirrors on your face), so that mica can form a good gloss.

　　Mica is widely used in the cosmetics industry as pearlescent agent to increase the brightness of products, or to brighten skin color on the skin surface, so that the skin has a better gloss.
