SUN MIROX by AGC Solar is extra clear extra thin glass for parabolic dish and parabolic trough collectors.

Roiceram™-Hs

Roiceram™-HS is High purity SiC components for solar cells. Roiceram™-HS has high thermal conductivity, high-strength, high-corrosion resistance, high-heat resistance

Applications

 

 

High heat-resistant ware for
phosphorus diffusion processes 

 

AGC's Roiceram material is ideal for making high purity SiC components. It is customized for semiconductor thermal process usage. Roiceram-HS has superb high temperature strength preventing softening or deformation in cycle use over 1200°C temperature range [i.e Diffusion process]. AGC applies the latest CNC machining technology assuring the highest level of dimensional accuracy in difficult to machine ceramic materials.
