Dielectric / Electrically Insulating Silica, Quartz, and Silicate Materials

Fused Silica Custom Shapes
from Accuratus Corporation

Fused silica is a noncrystalline (glass) form of silicon dioxide (quartz, sand). Typical of glasses, it lacks long range order in its atomic structure. It ’s highly cross linked three dimensional structure gives rise to it ’s high use temperature and low thermal expansion coefficient. [See More]

MACOR® Glass-Ceramic Bars -- 12" Length MACOR Bar
from San Jose Delta Associates, Inc.

Macor is a relatively easy material to machine using ordinary carbide drills, end mills, taps, etc. and doesn ’t require post machining firing. Macor-Machinable Glass Ceramic is also unique in that it can withstand 1000 °C, has low thermal conductivity and is a good electrical insulator. [See More]
