More info

Quartz Crucible is made from high-purity fused quartz ceramic, known for its fine microstructure, low thermal conductivity, and minimal thermal expansion. It offers excellent dimensional accuracy, stability at high temperatures, and strong resistance to thermal shock and chemical corrosion. Quartz crucibles are widely used in industries such as glass processing, metallurgy, electronics, chemicals, and aerospace. With the rise of solar energy, demand has surged for large, thin-walled square quartz crucibles in polycrystalline silicon production. Their stability and resistance to molten materials like silicon, aluminum, and copper make them essential for high-purity melting processes. Heeger Materials provides high-quality Quartz Crucibles with reliable performance and customizable specifications.
