Effect of crystalline phases on the strength of (quartz-feldspar-kaolin ) porcelain
Abstract
The effect of mullite and quartz phases on the strength of Kenyan tri-axial porcelain
in the system Quartz-feldspar-kaolin has been investigated. It was found that both the
compressive and tensile strengths of porcelain decreased with excess quartz content as a result
of circumferential cracks around quartz grains that may constitute fracture initiating flaws. The
interlocking effect of mullite was found to be more beneficial to the tensile strength than to the
compressive strength of porcelain
