Abstract:
Platinum-based composites are potential materials to substitute for platinum in some applications, for example, for containers in which to grow single crystal oxides. Ceramic coated platinum is the best material for crucibles as: first, the cylindrical geometry is suitable for coating with ceramic; second, the ceramic coating carries the basic mechanical loading, with the platinum acting both as the heater and anticorrosive coating; and third, refining this secondary platinum for recycling is neither a complicated nor expensive procedure. Plasma evaporation of alumina onto platinum is a technology that can be successfully applied to manufacturing commercial composite containers. In this paper the problem of cohesive strength between Pt and Al2O3, and the morphology and properties of the transition layer between the metallic matrix and the ceramic will be discussed.
