The aim of the present work is to explore the utilization of Algerian kaolin (DD2) and calcium carbonate (CaCO3) to synthesis of anorthite. Also, the effect of B2O3 addition on the properties of prepared anorthite was investigated. Compacted samples were sintered at temperatures between 1100 and 1300° for 2 h. All samples were characterized by X-ray diffraction, differential thermal analysis/thermogravimetric analysis, apparent density and open porosity measurements. The experimental results show the formation of anorthite in all samples. The increase in B2O3 ratio promoted the formation and the densification of anorthite at lower temperature.
