China, the United States, and Germany are the leading exporters of quartz (CAS 14808-60-7), collectively accounting for over half of global exports, while the United States, South Korea, and Japan are the largest importers, driven by demand in semiconductor and optical manufacturing. Export volumes from China have expanded steadily since 2022, coinciding with moderate upward pressure on quartz prices amid tightening supply of high-purity synthetic quartz.
Quartz is a naturally occurring crystalline form of silicon dioxide (SiO₂), appearing as transparent to translucent, hard, brittle, and lustrous solid crystals—commonly colorless, white, or tinted by impurities. It is chemically inert, non-volatile, odorless, and exhibits a high melting point of approximately 1650 °C (with polymorphic transitions below this temperature). Quartz is classified as an inorganic oxide mineral and is not used as a chemical intermediate in synthesis. Its primary industrial applications stem from its piezoelectric, optical, and thermal stability properties, making it essential in frequency-control devices (e.g., oscillators and resonators), precision instrumentation, semiconductor manufacturing, and high-purity laboratory ware. It is also employed in optical components, UV-transmitting windows, and as a raw material for fused silica production.
Silicon Dioxide is an anticaking agent, carrier, and dispersant that can absorb approximately 120% of its weight and remain free flowing. it is used in salt, flours, and powdered soups to prevent caking caused by moisture. it is also used in powdered coffee whitener, vanilla powder, baking powder, dried egg yolk, and tortilla chips. the usage level ranges from 1 to 2%. it is also termed silica, amorphous.
