Electric properties of anorthite ceramics prepared from illitic clay and oil shale ash

Abstract

Electrical properties during firing of anorthite ceramic prepared from mixtures of illitic clay

(from Northeastern Hungary) and fly ashes (obtained from circulating fluidized bed combustion e IA4 and pulverized firing e ID4) with high content of CaO were investigated.

Mixtures were prepared with 60 wt% of illitic clay and 40 wt% of oil shale ash. The ashes were hydrated prior to mixing, to prevent the reaction of free lime with water during sample preparation.
