Vapor pressure and evaporation rate of certain heat-resistant compounds in a vacuum at high temperatures
Technical Report
·
OSTI ID:5618881
The vapor pressure and evaporation rate of borides of titanium, zirconium, and chrome and of strontium and carbides of titanium, zirconium, and chrome, molybdenum silicide and nitrides of titanium, niobium, and tantalum in a vacuum were studied. It is concluded that all subject compounds evaporate by molecular structures except AlB sub 12' which dissociates, losing the aluminum.
