Product Details
Brief Introduction:
Huayuan synthetic mica is produced by hot melting method according to the chemical compositions and inner structures of natural mica. Synthetic mica forms through heating, melting, cooling and crystallization. The raw materials are blended, including quartz sand, potassium carbonate, aluminium oxide, potassium fluosilicate, fused magnesite and some other minerals. It has advantage of smoother surface, higher whiteness and purity. Synthetic mica is free from heavy metals that are harmful to human body.
