Product Description
Dental Lab Fused Silica Crucible,induction furances quartz crucibles
Fused quartz crucibles are made of selected fused silica as the main raw material and processed by
modern ceramic technology. It is mainly used for melting of platinum, gold, medical dental alloys and
other high-temperature alloys. The product has high purity and corrosion resistance. The content of the main component SIO2 is not less than 98%, the content of impurities (K2O, Na2O, Fe2O3) is not greater
than 70Mpa, the thermal shock resistance is high, and the repeated operation of 1100 ℃ --water
quenching is more than 10 times, and it is still intact,long life.
