Abstract

883,287. Crystalline glass. ZEISS-STIFTUNG, CARL., [trading as JENAER GLASWERK SCHOTT & GEN.]. Feb. 19, 1960 [April 8, 1959], No. 6018/60. Class 56. A crystalline sintered element is produced by mixing a powdered silica-containing glass with an inorganic salt capable of promoting crystallisation of the glass and heating to sinter and devitrify the mass. A suitable glass contains: SiO 2 , 54%; B 2 O 3 , 3%; Al 2 O 3 , 27%; divalent metal oxide, 16%. This is finely ground and mixed with one of the following, also finely ground-lithium carbonate, aluminate or silicate, magnesium carbonate or silicate, aluminium nitrate-together with an organic binder such as paraffin wax dissolved in carbon tetrachloride. The mass is pressed into shape and then heated, first to evaporate the solvent and then to decompose the binder. The latter may be accelerated by the addition of decomposable oxidising agent such as ammonium nitrate. Successively higher temperatures then sinter the mass and devitrify it.
