FUSED SILICA from Chemsize is made from high purity silica, under unique fusion technique,
thus ensuring its high quality. It is over 99% amorphous with extremely low coefficient of expansion,
and high resistance to thermal shocks. It is inert, has excellent chemical stability and extremely low electrical conductivity.
Because of these characteristics, FUSED SILICA finds many uses, including:
Investment Casting, Refractory and Ceramic applications.
