摘要: A borosilicate glass composition comprising 55-67 mol % of SiO.sub.2, 3-11 mol % of Al.sub.2 O.sub.3, 16-26 mol % of B.sub.2 O.sub.3, and 3-11 mol % of at least one oxide of SrO, CaO, MgO and ZnO is useful in the preparation of ceramic substrates. Since the amount of orthoboric acid formed on the glass in contact with humid air is minimized, the glass gives rise to little trouble in the manufacture of ceramic substrates. Ceramic compositions using the glass and a filler can be fired at low temperatures into sintered substrates which are characterized by a low dielectric constant, low dielectric dissipation factor, and high flexural strength.

摘要: A method and composition for protecting a gamma titanium aluminide alloy specimen subject to high temperature oxidation is disclosed. An alumino silicate glass coating is applied on the surface of the gamma titanium aluminide specimen. The coated specimen is heated to a temperature in a range of 2150.degree.-2250.degree. F. for a sufficient time period to form a silicide interfacial layer between the alloy and the glass coating. The glass coating is preferably a composition including SiO.sub.2 in a weight percentage of 60 to 65 Al.sub.2 O.sub.3 in a weight percent of 16 to 20. The glass coating results in minimal oxidation.
