摘要:
Disclosed are silica and fluoride doped lead-bismuth-gallium heavy metal oxide glasses for visible to mid-wave Infrared Radiation transmitting optics and preparation thereof. The glasses comprise in mol% 20-40 PbO, 5-20 Bi 2 O 3 , 10-30 Ga 2 O 3 , 30-50 SiO 2 , 0-20 PbF 2 , 0-20 ZnF 2 , 0-20 InF 2 , and 1-20 PbF 2 + ZnF 2 + lnF 2 .
摘要:
Disclosed are a phase separable glass compositions used to produce chemically durable porous glass, e.g., porous glass powder, and the application of a sol gel coating to the glass to enhance chemical durability of the glass in alkaline solutions, and to the use of the glass, e.g., glass powder, as substrates for separation technology where harsh alkaline environments (pH ≥ 8 e.g., pH 12-14) are routinely prevalent.
