Quartz, commonly referred to as Fused Silica, is a non-crystalline, high-purity form of silicon dioxide (SiO₂) known for its exceptional thermal shock resistance, optical transparency, and chemical durability. We provide high-precision CNC machining of quartz components used in semiconductor, optics, laser, and high-temperature environments.
Fused Silica is a vitreous form of silica produced by melting high-purity sand or synthetic precursors. It combines the thermal stability of ceramics with the optical clarity of glass, making it ideal for UV to IR applications, and for harsh chemical or vacuum environments where purity and stability are critical.
We offer CNC machining for high-purity sintered Quartz.
