Abstract

Abstract : This work focuses on the effect of β -wollastonite percentage with different particle sizes on the bulk density and weight loss of clay-based ceramics. The ceramic bodies were prepared by mixing clay with a synthesized β -wollastonite (5%, 15%, and 25%) using a solid slip casting method. The clay (75 µ m) and β -wollastonite (63, 75, and 125 µ m) were mixed and fired at 950°C, 1000°C, and 1050°C of firing temperatures. The fabricated ceramic material exhibited a maximum bulk density of 2.35 g/cm 3 on 25% content of β -wollastonite, 63 µ m particle size of β -wollastonite, and 1050°C of firing temperature. However, a minimum bulk density of 1.87 g/cm 3 was found on 25% content of β -wollastonite, 125 µ m particle size of β -wollastonite, and 950°C firing temperature. A minimum of 2.32% ignition loss was recorded on a ceramic specimen that contained 25% of β -wollastonite with a particle size of 125 µ m and fired at 950°C of firing temperature. In contrast, a maximum of 4.37% ignition loss was observed at a ceramic body made up of 5% of β -wollastonite content with 63 µ m particle sizes and fired at 1050°C. In general, the result shows that the firing temperature, the particle size of β –wollastonite, and the addition of β –wollastonite have a great effect on the bulk density and ignition loss of the clay ceramic materials.
