    Abstract: This invention relates to the discovery of a method for incorporating various oxides into silica-containing porous and nonporous glass materials by dissolving soluble compounds of the additive oxides, characterized as MxOy, into solutions, colloidal solutions, or suspensions of soluble silicates, reacting the mixture with an organic compound, and then firing the thus-formed body at temperatures below the softening point of the particular glass composition for a sufficient length of time to produce the porous body or non-porous glass body containing the added oxides intimately bonded to the silica network.

    Abstract: An alkali free glass has an average coefficient of thermal expansion at 50 to 350° C. of 30×10−7 to 43×10−7/° C., a Young's modulus of 88 GPa or more, a strain point of 650 to 725° C., a temperature T4 at which a viscosity reaches 104 dPa·s of 1,290° C. or lower, a glass surface devitrification temperature (Tc) of T4+20° C. or lower, and a temperature T2 at which the viscosity reaches 102 dPa·s of 1,680° C. or lower. The alkali free glass contains, as represented by mol % based on oxides, 62 to 67% of SiO2, 12.5 to 16.5% of Al2O3, 0 to 3% of B2O3, 8 to 13% of MgO, 6 to 12% of CaO, 0.5 to 4% of SrO, and 0 to 0.5% of BaO. MgO+CaO+SrO+BaO is 18 to 22%, and MgO/CaO is 0.8 to 1.33.

    Abstract: A preparation method of rare earth ions doped alkaline earth metal silicate luminescent glass is provided. The steps involve: step 1, mixing the source compounds of cerium, terbium and alkaline earth metals and putting the mixture into solvent to get a mixed solution; step 2, impregnating the nanometer pores glass with the mixed solution obtained in step 1; step 3: calcining the impregnated nanometer pores glass obtained in step 2 in a reducing atmosphere, cooling to room temperature, then obtaining the cerium and terbium co-doped alkaline earth metal silicate luminescent glass. Besides, the rare earth ions doped alkaline earth metal silicate luminescent glass prepared with aforesaid method is also provided. In the prepared luminescent glass, cerium ions can transmit absorbed energy to terbium ions under the excitation of UV light due to the co-doping of cerium ions. As a result, the said luminescent glass has higher luminous intensity than the glass only doped with terbium.
