Abstract

The questions of applying the organoaluminum and yttrium aluminum binders when fabricating high-thermostable ceramic corundum molds are considered. This technology is a promising direction in the formation of ceramic shell molds for intricately shaped high-duty investment castings made of titanium alloys. The use of silica-free binders, which possess a series of advantages when compared with many currently widespread ones, in casting houses makes it possible to solve many questions associated with the thermochemical stability of ceramic forms, as well as to decrease the volume of finish operations and rejects during casting parts made of chemically active metals and alloys, thereby providing an increase in the quality of exact important castings.
