Abstract
The study covers organoaluminum and yttrium aluminum binder application in the production of high-heat-resistant ceramic corundum molds. This technology is a promising trend in the manufacturing of ceramic shell molds for precision casting of intricate shape high-duty investment parts of titanium alloys. Foundry shop applications of silica-free binders having a number of advantages over most popular ones at the moment addresses many issues associated with thermochemical stability of ceramic molds and reduces the scope of finishing operations along with rejection rate when casting parts of reactive metals and alloys, thus providing improved quality of high-duty investment castings.
