RESEARCHING OF PHOSPHORUS SLAG FOR PRODUCING ZINC-PHOSPHATE COMPOSITE CEMENT

Abstract

The cements required for dentistry are not produced in our country, and all their types are imported from abroad. The scientific article examines the possibility of producing zinc phosphate dental cement and the composition of the phosphorus slag added to it. Phosphorus oxide and fluoride oxide present in the phosphorus slag play an important role as activators in the production of dental cement. In addition, the chemical composition of the phosphorus slag was determined, their X-ray phase and differential thermal analyses were carried out. In the differential thermal analysis of pseudowollastonite, the exothermic effect is observed at a temperature of 920 °C.
