Application Overview of Synthetic Fluorphlogopite
Artificially synthesized fluorphlogopite flakes KMg3(A1Si3O10)F2 (also known as synthetic mica) are made of chemical raw materials , mineral raw materials undergo high-temperature reaction, melting, cooling, crystallization, and growth, and sodium bicarbonate is formed into a layered silicate compound. It does not contain hydroxyl groups, so it has good temperature resistance and good insulation; it is directly fired from compounds, so it has high purity and whiteness. The prepared synthetic fluorphlogopite powder is widely used in mica titanium pearlescent pigments, cosmetic powders, plastics and ceramic fillers. At the same time, the synthetic fluorphlogopite is widely used in the electronics industry due to its excellent electrical insulation properties.
Applications of synthetic fluorphlogopite
CN201710534173 reports a method for preparing artificially synthesized fluorphlogopite powder coated with nanometal silver, which includes the following steps: (1) Pretreatment of artificially synthesized fluorphlogopite powder, including: (1-1) coarsening ; (1-2) Activation, first use liquid precipitation method to coat the first activation layer on the roughened synthetic fluorphlogopite powder. The chemical composition of the first activation layer is SnO2 , SiO2 or ZnO; then use liquid phase precipitation method to coat the second activation layer on the first activation layer. The chemical composition of the second activation layer is TiO2, CaO, Al2O3 or ZrO2; (2) Prepare silver ammonia solution; (3) Through silver mirror reaction, after activation The synthetic fluorphlogopite powder is coated with a nanometer metallic silver layer. The nanometer metal silver-coated artificially synthesized fluorphlogopite powder prepared by the invention has excellent conductive and thermal conductive catalytic properties, excellent decorative properties, high strength, high toughness, good chemical resistance, non-toxic and impurity-free, light texture and other excellent properties. , low cost and high cost performance.
Application of fluffing of synthetic fluorphlogopite
CN201310355762 reports a method for fluffing artificially synthesized fluorphlogopite mica flakes, which includes the following steps: soaking the artificially synthesized fluorphlogopite mica flakes in water; disposing alkali metals containing carbonate or bicarbonate in the water in the above steps. Inorganic salt solution, let the synthetic fluorphlogopite flakes be soaked in it at 25 degrees Celsius; pour the above-mentioned carbonate or bicarbonate-containing alkali metal inorganic salt solution containing the synthetic fluorphlogopite flakes into the ammonium-containing inorganic salt solution Or carry out a chemical reaction in an organic solution containing NH2– to preliminarily expand the cleavage surface of the artificially synthesized fluorphlogopite flakes; take out the above-mentioned preliminarily expanded artificially synthesized fluorophlogopite methyltetrahydrofuran mother flakes , perform calcination to further fluff the synthetic fluorphlogopite flakes, and obtain fluffy synthetic fluorphlogopite flakes. The present invention effectively peels off the cleavage planes between the artificially synthesized fluorphlogopite flakes through physical state changes during the chemical reaction process, thereby providing a good prerequisite for wet grinding.
