All the raw materials for each batch and the formula can be controlled, which guarantees the quality consistency of each batch. Due to the mine is formed for millions of years, the quality of each mica mine is quite different. Even though in a same mine, the quality is hard to keep consistency. Thus, the quality of each batch is different. Radicalization Synthetic mica is synthesized artificially so that it is free from natural radiation. Most of ores are more or less with radiation as the mine was formed through millions of years. Purity Synthetic mica is a crystallized combination produced according to formula. The raw materials are by severe screening, which guarantees the high purity. The mica is formed by natural powder so that it is with many mineral impurities. Meanwhile, it gets pollution during mining. The purity is much less than synthetic mica. Heavy metal content Sanbao synthetic mica has been proved by SGS that is nearly free from heavy metal. It meets the safety index of European Union, U.S., etc. developed countries. Natural mica is with many harmful heavy metal to human health. Appearance Smooth surface. High whiteness(>92). It has worse surface smoothness and looks grey. The whiteness is about 60 - 80. Heat-resistance The melting point of synthetic mica reaches（1350±5）℃. Generally at 200 ℃, the layers start to stratify and the color changed. Electric property Dielectric strength: 185-238 kV/mm Dielectric strength: 115-140 kV/mm Insulation property Surface resistance:Ω 3×1013 Surface resistance:Ω 1×1011 Tensile strength Mpa 150 110-140 （OH）Bond Synthetic mica is OH Bond free. It is not like the natural mica would release harmful hydrogen to steels. Thus, it can be used to antirust metal products.   Optically transparent rate Synthetic mica crystal is colorless and transparent that has better optically transparent property against infrared and ultraviolet radiation than natural mica does. So the synthetic mica based pearl pigment is quality.   4.The main characteristics between synthetic mica and natural mica：   unit Synthetic mica Phlogopite muscovite density g/cm3 2.7-2.85 2.75-2.90 2.70-3.00 dielectric strength kv/mm 185-238 115-140 110-130 Volume resistivity Ω.cm (3-6)×1015 1013-1014 1014-1015 surface resistivity Ω 3×1013 1010-1014 1011-1012 dielectric constant ε 5.8-6.3 5.0-6.5 6.0-8.0 dielectric loss tgδ（M C） 3.38×10-4 (20-70)×10-4 (2-10)×10-4 tensile strength kg/cm2 1500 950-1300 1100-1500 water absorption % 0.14 2.7 2.2 Moisture absorption rate % 0.04 0.24 0.18 heat resistance ℃ 1100-1300 600-650 350-450
