Abstract
The purpose of this investigation was to study the effect of changes in composition and thermal history on some properties of potential leucite-glass composites made by a coprecipitation process. Four compositions from the K2O–Al2O3−SiO2system were investigated for differences in phases, density, thermal expansion, and strength. Strength, density, and thermal expansion increased with increasing leucite content. Strengths of up to 140 MPa were obtained with air-fired specimens. Composites with different thermal expansion coefficients could be obtained by altering SiO2content in a predictable way. Leucite-glass composites offer potential for improved dental porcelains.
