SiLibeads® Glass Beads
have proven themselves in a wide variety of applications, e.g. mixing pharmaceutical products, filtering water or to protecting spirits bottles from contamination
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.
Fields of application
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.
Advantages
- Highest chemical purity with SiO2 content ≥ 99.98 %
- Highest chemical resistance of all glass types (hydrolytic class HGB 1, acid resistance class S1 and alkali resistance class A1)
- High light transparency from IR to UV wavelength range (170 – 5000 nm)
- High roundness of beads dMIN / dMAX ≥ 0.95
- Very high service temperature of 1100 °C (1300 °C also possible for short periods)
- Very high thermal shock resistance
