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.

Es werden bismuthaltige Gläser mit Germaniumoxidzusätzen angegeben, bei denen der Gehalt von B 2 O 3 und SiO 2 grösser als 0,1 jedoch kleiner als 5 Mol-% ist. Ferner wird ein geeignetes Herstellverfahren angegeben. Die Gläser sind bei Dotierung mit seltenen Erden insbesondere als optisch aktive Gläser verwendbar.

摘要:
The invention relates to an optical scattering element suitable for dispersing or scattering light transmitted by optical device by Mie scattering. The optical scattering element comprises a phase-separated or porous borosilicate glass having dispersed phase particles with a particle size of 200 to 500 nanometers or pores with a size of 200 to 500 nanometers, at a number density of 10 8 to 10 12 mm -3 . The optical scattering element can be prepared by subjecting a borosilicate glass to a controlled heat treatment to induce phase separation, and then optionally leaching out one of the phases with an acid leach. The optical scattering element can be, for example, attached to an end of an optical fiber or bundle of optical fibers. The invention also relates to a method of dispersing or scattering light by transmitting the light through the optical scattering element.
