Making of Fused Silica: Electric Fusion

Dinglong has been producing fused silica on an industrial scale with the electric fusion melting process. More specifically, Dinglong uses the batch fusion method of electric fusion. In the batch fusion method, a large quantity of raw material is placed inside a refractory lined vacuum chamber which also contains heating elements. Although this method has historically been used to produce large single boules of material, it can also be adapted to produce much smaller, near-net shapes.

Processing of Fused Silica: Mechanical Processing

Due to its hardness, fused silica requires diamond tools to process it mechanically. Because it is fragile, there is a limit to the force it can withstand before cracking and resulting from that the feed speed during processing needs to be chosen carefully.
