Features:
1.The ideal raw material: Fused silica
2.Our crucibles are made of fused silica,highly purity(SiO2>99%)
3.Very low expansion coefficient,giving it an extraordinary resistance to the thermal shock.
4.Low sensitivity to metal oxides,ensuring lasting resistance to the corrosion caused by dental alloys.
5. for flame fusion machines.
