Fused quartz - Wikipedia

Fused quartz is normally transparent. The material can, however, become translucent if small air bubbles are allowed to be trapped within. The water content (and therefore infrared transmission of fused quartz and fused silica) is determined by the manufacturing process. Flame-fused material always has a higher water content due to the combination of the hydrocarbons and oxygen fuelling the furnace, forming hydroxyl[OH] groups within the material. An IR grade material typically has an [OH] content below 10 p…US20120098169A1 - Process for manufacturing high,Fused silica ceramics plays demanding role in high velocity missile/aircraft'radome development. Slip casting is the most common and commercially viable process utilized for radome production. Unfortunately slip casting cannot afford high density due to its poor green packing density which in turn results in poor rain erosion resistance.What is the production process of Fused Silica Mirrors?,Fused quartz or quartz glass is an amorphous form composed of quartz. It differs from traditional glass in that it has no other ingredients and is usually added to the glass to lower the melt temperature.
