Diffusion cassettes

Diffusion cassettes

Fibrothal® diffusion cassettes are a 'plug and heat' solution for the production of high-quality crystalline silicon wafers for solar cells and semiconductors. The diffusion cassettes are of low mass design type with vertical or horizontal elements for operating temperatures up to 1350°C (2460°F). Customized heaters for specific applications can be delivered on request.
