Properties of highly refractory corundum ceramics containing glass phase, and their influence on the surface roughness after mechanical treatment
Systematic investigations were made of the effect of the content of silica additives in the form of aluminosilicate raw materials, synthetic glasses, (aluminoborosilicate), and also pure silicon dioxide and mixtures of it with magnesium, calcium, yttrium, zirconium, chromium oxides, and zircon concentrate on the formation of glass phase and the content in it of SiO/sub 2/, the mechanical strength and impact strength of the ceramics and their abrasion resistance. A study was also made of the relationship between these properties and the state of the surface finish of the ceramics after mechanical treatment. The study showed that the amount of glass phase formed after firing and the content in the glass phase of silica are determined by the concentration of silicon oxide contained in the additive.
