The synthetic mica flake is also called synthetic fluorophlogopite mica flake. It is made from the raw chemicals through highheating fuses,cooling and crystallizing.The functions of the synthetic mica flake is superior to the natural mica, for example,high temperature resistivity can reach above 1300°C.Under high temperature conditions,the synthetic fluorophlogopite mica’s electric volume resistivity is 1000 times higher than the natural mica. It has a lot of advantages，for example,electrical insulation is excellent,high-temperature gas releasing under the vacuum condition is highly effective, besides,it has the following characteristics well alkali-resistant,transparent,elastic, which can be layered detachment. It is also the most important non-metallic insulation materials in electrical,electronics,aviation and other important modern industries.
