STUDY OF THE INFLUENCE OF B2O3 OXIDE ON THE PHYSICAL AND TECHNICAL PROPERTIES OF GROUND ENAMEL OBTAINED BASED ON LOCAL RAW MATERIAL COMPONENTS

The purpose of the study was to obtain ground enamel based on local raw materials and to study the effect of boron oxide. The selection of local raw materials for producing ground enamel showed that the resulting glass compositions are in the SiO2–Al2O3–Na2O–K2O–CaO–B2O3 system. To adjust the properties, additives of nickel oxide and cobalt oxide were used. The properties of the developed compositions of primer enamels meet the requirements of GOST 24405-80. It has been determined that the addition of boron and an increase in its amount in the glass composition increases spreadability and reduces surface tension. The study of the structural features of the synthesized glasses using IR spectroscopy made it possible to establish the presence of 4-fold coordinated boron and the appearance of 6-fold coordinated boron compounds with increasing its content.
