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.
