ZGS Platinum is a grain stabilized platinum containing a small amount of highly dispersed zirconium oxide. Its properties combine to provide greater high-temperature strength and, in some applications, greater contamination resistance than that of pure platinum. Applications include laboratory crucibles and dishes. An exacting application is in the production of fibre glass which invloved the rapid flow of molten glass at temperatures of 1250-1350 C through a pierced plate which must retain its shape and alignment. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, and tensile properties as well as creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Pt-2.

ZGS 5% RHODIUM-PLATINUM is a zirconia grain stabilized (ZGS) platinum alloy. The ZGS alloys are used to contain molten glass, one of the most corrosive materials known to man. ZGS Platinum (Alloy Digest Pt-2, May 1975) and ZGS 10% Rhodium-Platinum (Alloy Digest Pt-3, March 1979) have been covered previously. ZGS 5% Rhodium-Platinum was developed to provide a cheaper alloy than ZGS 10% Rhodium-Platinum alloy but with considerably higher high-temperature strength than ZGS Platinum. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, and tensile properties as well as creep. It also includes information on forming, heat treating, machining, and joining. Filing Code: Pt-4. Producer or source: Johnson Matthey.

ZGS 10% Rhodium-Platinum is a grain stabilized platinum-base alloy containing a small amount of highly dispersed zirconium oxide. Its production and general characteristics are closely related to those of ZGS Platinum which also is strenghtened by highly dispersed zirconium oxide (Alloy Digest Pt-2, May 1975). ZGS 10% Rhodium-Platinum is significantly stronger at high temperatures and more creep resistant than the conventional high-temperature rhodium-platinum alloys, while retaining their useful electrical and chemical properties. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, and tensile properties as well as creep. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Pt-3. Producer or source: Matthey Bishop Inc..
