ABSTRACT: Andalusite (Al2O3 SiO2) is a member of the alumino-silicate minerals. Because of having excellent high temperature volume stability, mechanical strength, thermal shock resistance and creep resistance, the refractories made from andalusite have been used in many industrial fields, such as metallurgical industry, building materials industry, and others [1-7] . Although mullitization and sintering properties of andalusite concentrate powder have been studied by some scholars[8-11], the reports about applied research of alumina in high-purity andalusite based refractory have not been seen. Aiming at the development of high performance andalusite based refractory products, this paper probes the effects of the addition of selected samples some of alumina on microstructure, phase composition and specified physical properties of high-purity andalusite based refractory (hereafter abbreviated to HPABR).
