Borosilicate Glass Wafers

Borosilicate Glass Wafers

Production

Float glasses are glass sheets made by floating molten glass on a bed of molten tin. Hereby the molten glass forms a floating both-side smooth ribbon with a homogeneous thickness. On its way on the tin bath, the temperature is gradually reduced from 1100 down to 600°C until the sheet can be lifted onto rollers.

After further cooling down the glass gradually to room temperature, so that it anneals without strain, the sheets are cut into the desired dimesions.

Available diameters are 2, 3, 4, 5, 6 and 8 inch. Other diameters as well as

rectangular wafer pieces on request. Please also have a look at our stock list

Wafer Thicknesses

Standard thicknesses of fused silica wafers are 500, 700 and 1100 µm. Other

thicknesses on request.

Surface
