Natural Large Crystal Green Mica Scrap For Decoration

Green mica scrap,the most common form in mica, whose chemical formula is KAl2(AlSi3O10)(OH)2, are mained from raw ores.It has obvious layered structure and it is fairly light and relatively soft.Mica is an important rock-forming mineral present in igneous,metamorphic, and sedimentary rocks. As a natural silica, Mica is a very special functional filler due to its high lamellar structure and purity. Mica is chemically inert, resistant to most acids and oxidation, insoluble in water and has a high temperature resistance. It also shows excellent electrical insulation performance.
