Summary:

High purity quartz sand - synthetic series refers to quartz sand products synthesized through specific processes with extremely high SiO ₂ content (usually greater than 99.9% or even higher) and extremely low impurity content (such as Fe ₂ O3, Al ₂ O3, etc., with much lower content than natural quartz sand).

Characteristic:

It has extremely high purity, excellent physical and chemical properties (such as high heat resistance, low thermal expansion, high insulation, and transparency), stable chemical stability, and good processing performance.
