Глазурні покриття для клінкерної кераміки

Abstract

It presents the results of the development the non-fritted glazes compositions for ceramic clinker brick. Base glazes made inexpensive raw materials - silica sand, clay, pegmatite, chalk, glass fight. The benefits of these glazes are simplicity and accessibility of the implementation on a typical brick factory. These non-fritted glazes should be applied to the raw semifinished product that provides an economical single firing bricks. Attention is drawn to the decision consistency of shrinkage processes occurring during the formation of the vitreous layer on the surface of the ceramic substrate. Are the different types of defects that can occur when the wrong-chosen composition of the glaze or violation of technological regime. It brought a lot of pictures of the microstructure of coatings, which illustrate the effect of different components of the change on the formation of glaze layer.
