text: Fused silica itself is an excellent glass, but, as the melting point of sand (crystalline silica) is above 1,700 °C (3,092 °F) and as it is very expensive to attain such high temperatures, its uses are restricted to those in which its superior properties—
text: Fused Silica is an excellent thermal insulator.
text: Fused Silica is an excellent electrical insulator well into the microwave, with a dielectric loss factor of under 0.0004 at 1 MHz.
