Fused Quartz / Fused Silica Hard Machining Material …
Fused silica grades termed UV grade are better controlled from these metals, and so they transmit further into UV ranges. But their drawback is OH caused absorption, especially at 2.2um and 2.7um. All SiO2 glasses share some properties, including extreme hardness, very low thermal conductivity, low thermal expansion, and a wide range of optical transmission from UV to IR.
Thermal Conductivity of Metals and Alloys | Neutrium
Thermal conductivity measures a materials ability to allow heat to pass through it via conductance. The thermal conductivity of a material is highly dependent on composition and structure. Generally speaking, dense materials such as metals and stone are good conductors of heat, while low density substances such as gas and porous insulation are poor conductors of heat.

The low average thermal conductivity of the spacer segment, of less than 2 W/mK, results in a reduced heat loss. Fused silica in particular, within a temperature range between 20 and 500° C., has an average thermal conductivity of only 1.7 W/mK and is therefore able to reduce significantly the heat loss via the generally cooled reactor top and/or reactor bottom.
