Andalusite has a low impurity level but high silica content of 3840 %. The grains are Andalusite crystals and have practically no open porosity. Andalusite is mined in South Africa (245,000 tpa), France (65,000 tpa), and China (small domestic use). New mining projects are ongoing in Peru (plan 60,000 tpa [7]) and Mongolia. The global

Xsialon formation by the combination of mechanical activation and silicothermal reduction and nitridation (SRN) process was investigated. The starting materials (andalusite, Si and alumina) were activated in a planetary mill and two kinds of milling cups and balls were utilized. Samples were characterized by XRD, SEM and DSC. Milling with steel equipment inhibited nitridation.

Olivine powders were milled alone or blended with 20, 40, 60 and 80 wt% of highgrade kaolin (% of Al 2 O 3) by attrition milling to obtain powders of different compositions. The materials fired at their optimal temperature ( °C) could represent an option for a possible recycling of waste olivine into the production of tiles.

About Andalusite. A ndalusite is an aluminasilicate raw material used principally in the manufacture of heat resistant refractory products. When andalusite is produced, unlike many other refractory raw materials, costly calcining is not required. Typical physical/chemical characteristics of the Peruvian andalusite are 59% Al2O3 and Fe2O3 %.

As with andalusite and kyanite, sillimanite is a feedstock mineral for conversion to mullite Al 6 Si 2 O 13 (see extended discussion in Andalusite, Applications chapter). It is considered the best raw material for manufacturing refractory bricks of 55 60% alumina. Its largescale use is precluded, however, because of its cost.
