Synthesis and Characterization of Free-CaF2 Mold Powder Containing Ceramics Compounds as TiO2, B2O3, ZnO and Na2O

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.
