ABSTRACT:
A method of forming titanium calcium oxide is disclosed comprising the steps of mixing titanium hydroxide, calcium hydroxide, and water in an autoclave, then heating these reaction constituents at a selected temperature and pressure for a time to allow the formation of titanium calcium oxide crystals of a desired size. Next, pressure in a receiving vessel is set below the pressure in the autoclave, and a valve is opened to allow the reaction product to flow from the autoclave to the receiving vessel at a constant flow rate. Heat is removed from the reaction product while the reaction product passes through a flow passage between the autoclave and the receiving vessel. This process can be modified to form zirconium calcium oxide.
