Silgrain® PreSize

Silgrain® PreSize is a silicon powder developed to give maximum yield in the thermal spraying process for the production of sputtering targets used in the glass industry. The particle size distributions of our Silgrain® PreSize products are produced with both a well-defined bottom cut and top cut.

Description

Silgrain® PreSize is a silicon powder produced in two main qualities: Silgrain® PreSize and Silgrain® Solar PreSize. 

Application

The main application for Silgrain® PreSize qualities are as a raw material for the production of sputtering targets used in glass coating and electronic industry. Our Silgrain® PreSize qualities are tailor made for thermal spraying processes. 

Sizes

Silgrain® PreSize qualities are produced with both a well-defined bottom cut and top cut. Typical size is 40-120 µm. Particle size distribution curves and D10, D50 and D90 values can be supplied upon request. Contact us if other closed particle size distributions is needed. 

Packing

Silgrain® PreSize qualities can be delivered in 1000 kg big bags or 125 kg steel drums. Other non-standard packaging on request.
