DIFFUSER MATERIAL OF SYNTHETICALLY PRODUCED QUARTZ GLASS AND METHOD FOR THE MANUFACTURE OF A MOLDED BODY CONSISTING FULLY OR IN PART THEREOF

A diffuser material of synthetically produced, pore-containing quartz glass and a method for the manufacture of a molded body consisting fully or in part thereof. The diffuser material has a chemical purity of at least 99.9% SiO2, a cristobalite content of not more than 1%, and a density in the rang...

description A diffuser material of synthetically produced, pore-containing quartz glass and a method for the manufacture of a molded body consisting fully or in part thereof. The diffuser material has a chemical purity of at least 99.9% SiO2, a cristobalite content of not more than 1%, and a density in the range of 2.0 to 2.18 g/cm3. Starting therefrom, to indicate a diffuser material which is improved with respect to diffuse reflectivity with Lambertian behavior over a wide wavelength range, high material homogeneity and UV radiation resistance, the quartz glass has a hydroxyl group content in the range of at least 200 wt. ppm and at least 80% of the pores have a maximum pore dimension of less than 20 μm.
