Abstract
863,569. Ceramic glass. CORNING GLASS WORKS. Dec. 21, 1959 [Dec. 31, 1958], No. 43354/59. Class 56. Semi crystalline bodies are made by melting a batch of glass of the type R 2 O BaO SiO 2 where R represents Na, K or Li, or Li 2 O. Al 2 O 3 . SiO 2 , including in the batch a compound of at least one of the noble metals Ru, Rh, Pd, Os, Ir and Pt in an amount to produce 0À001-0À10% by weight of the metal, computed as free metal, shaping the molten glass and heat treating the glass body by raising its temperature to between 580‹C. and 650‹C. and holding it for a time ranging from about 8 hours at 580‹C. to about ¢ hour at 650‹C. Preferably the temperature is then raised to between 700‹C. and 850‹C. and held for a time ranging from about 8 hours at 700‹C. to about 1 hour at 850‹C. Glasses are of the general compositions in weight percentage (1) SiOz 50 and 85; BaO 3 to 45; alkali metal oxide 5 to 25 of which LizO is 0 to 25 ; NazO O to 10 ; K 2 O O to 10, the total Na 2 O+ KzO being not more than 15 when the BaO exceeds 20 nor more than 8 when the BaO is less than 20 ; 0 to 10 of oxides of metals other than Ba of the 2nd periodic group, the total with BaO not exceeding 45 and Al 2 O 3 0 to 10, the total of these oxides being at least 95 ; and (2) SiOz 60 to 85 ; Al 2 O 3 2 to 25 ; LizO 6 to 15 the ratio Al 2 O 3 /Li 2 O being less than 1À7, and NazO and/or K 2 O 0 to 4, the total of these oxides being at least 97. A number of examples of suitable batches are given. The glass may be used as bearings, thread guides, dishes, tableware and tile and wall panels. Specifications 752,243, 829,447 and 863,570 are referred to.
