Fused silica melting crucible, quartz smelting crucible bowl for gold and platinum

Category：

Fused Silica crucible

Product description

Product introduction：

Selected quality quartz as materials,combined with advanced ceramic processing workmanship,mainly used for melting platinum , gold , silver ,copper and other high temperature alloy ,high purity, anti-corrosion,anti strong acid and strong alcali ,good hardness,high thermal shock resistance. The main component is SiO2 ≥80%, Al2O3 (≤17%) and other is 3%( K2O,Na2O,Fe2O3) , There is no crack after 10 times sudden heat and sudden cold at 1100℃⇌ 20℃,and no crack after 10 times using oxygen cutting gun to spray 1700-1800 flame on the crucible.
