The article describes the development of a procedure for the preparation of foundry ceramic moulds and making first test castings. The presented studies included: - development of technological parameters of the ceramic mould preparation process using water-based zirconium binders and zirconia ceramic materials, where moulds are next used for the centrifugal casting of titanium alloys melted in vacuum furnaces, - designing of pouring process using simulation software, - making test castings, - testing and control of the casting properties. The technological process described in this paper enables making castings in titanium alloys weighing up to about 500 g and used in the majority of technical applications.
