Type Q

Polished glass beads made of quartz glass (synthetic silica glass) to form a high-purity grinding bead.
Type Q glass beads made of high-purity synthetic silica glass are formed into beads and then sintered in a defined manner.

Use as ultra-pure beads for cell disintegration and autogenous grinding; grinding of conductive pastes, glass paints and high-purity silicate materials; in the laboratory as carrier material with bioactive or catalytic surface; as filler material in the cosmetics industry, semi-conductor industry and pharmaceutical industry; as radiation conductor in the UV range (disinfection); optical sphere/half sphere for UV sources/wave guides; photovoltaic sphere with transmission of 170 – 5,000 nm; filter material for very high temperatures and many other applications.
