ABSTRACT: The article considers one of the possible
approaches to the solution of an urgent issue of metal consumption reduction,
increase of operating life and maximum operating temperature as well as
reduction of irrecoverable losses of platinum products and alloys when
operating under high temperature conditions, particularly for glassblowing and
single crystal growing crucibles. A two-layered composite material based on
platinum-group metals and corundum plasma ceramics is thoroughly investigated.
A successful experience of crucibles exploitation, designed for production of
high temperature optical glasses from the composite and results of the research
on composite material specimens are described.
