Sintered Zirconium Silicate Beads
Zirconium Silicate for low to medium viscosities and general milling-economical step up from glass.
 
Zirconium Silicate Ceramic Beads is manufactured by electric/thermal fusion of oxides. The internal structure is made up crystalline ceramic phase bonded by an amorphous silica phase resulting in high impact properties coupled with good hardness.
Zirconium Silicate Ceramic Beads is used for surface cleaning of rubber and plastic molds, castings, boiler and heat exchanger parts, shot peening of components and also in nuclear reactor components like exchanger tube plates prior to welding.
Zirconium Silicate Ceramic Beads is also used for deburring locks and lock components and surface preparation of stainless steel parts used in the food industries.
Applications:
1. It maybe used in airless and compressed air blasting equipment, both wet and dry.
2. When used in airless blasting equipment, sufficient media coverage of the blades must be maintained to avoid excessive media breakdown rates.
3. Ensure blasting equipment contains a good operating mix if removal of
millscale / discolouration is required.
