Originální abstrakt

The aim of the article is to describe the sintering activity of industrially milled sodium potassium feldspar to determine of optimal firing temperature during fast firing typical for e.g. production of dry pressed ceramic tiles. The change of porosity, flexural strength, firing shrinkage and mineralogical composition in dependence on the firing temperature (1120 - 1210 degC) were determined on the test samples made from dry granulate prepared from the pure feldspar. Tested alkali sodium potassium feldspar is characterized by low sintering temperature (1190 deg C) during fast firing (heating rate 10 degC/min). During the sintering process, feldspar gradually disappears in phases first of all potassium feldspar (microcline), sodium feldspar (albite) we can find in the fired body at firing temperature 1180 deg C.
