Question

what is the material medium of fused quartz​

Answer 1

Answer:

Fused quartz or fused silica is glass consisting of silica in amorphous (non-crystalline) form. It differs from traditional glasses in containing no other ingredients, which are typically added to glass to lower the melt temperature. Fused silica, therefore, has high working and melting temperatures.

Answer 2

Answer:

Manufacture. Fused quartz is produced by fusing (melting) high-purity silica sand, which consists of quartz crystals. ... Type II is produced by fusing quartz crystal powder in a high-temperature flame. Type III is produced by burning SiCl4 in a hydrogen-oxygen flame
