In this research, the aim is the synthesis and characterization of a free-CaF₂ mold powder via Ceramics Compounds such as TiO₂, B₂O₃, ZnO and Na₂O. For this purpose, in this research, 12 powder samples were prepared using compounds such as TiO₂, B₂O₃, SiO₂, Na₂O, ZnO, Li₂O, CaO, MgO, MnO, K₂O, CaF₂ and Portland Cement Clinker. To characterize laboratory samples, groove viscometer test, XRD, SEM and STA analyses were used. Results showed that with the formation of phases such as gehlenite, akermanite, nepheline, provskite, Na₂ZnSiO₄ and B₂SiO₅, the formation of crystalline particles in glass matrix, conformity crystallization and melting temperatures of the  free-CaF₂ sample with crystallization, and melting temperatures of original mold powder, a free-CaF₂ mold powder was synthesized and characterized via TiO₂, B₂O₃, ZnO and Na₂O. This powder was developed in laboratory scale, and the viscosity and the crystallization of the powder was the same as those of the original powder. This sample of mold powder can be a suitable replacement for the original powder.
