Quartz Powder
Quartz Powder is a processed mineral material valued for its silica content, hardness, and suitability for a wide range of industrial formulations. Its produced by finely grinding high-purity natural quartz with a typical SiO₂ content of 98.5% or higher. It is chemically inert, hard (Mohs 7), and highly thermally stable.
