Abstract

Feldspar concentrates produced from concentrated rocks of Karelia are investigated as components of hard porcelain mixtures. The effect of feldspar concentrates having different ratios of potassium and sodium oxides, the mineralogical composition, and the structural specifics on the structure and properties of porcelain mixtures is studied. It is established that the grain structure and the ratio of quartz and feldspar in the concentrate have a great significance for the formation of the vitreous phase in the fired sample.
