Resumen de Imerys to enhance its andalusite footprint
"Andalusite based bricks show good creep behaviour at high temperatures compared to bauxite-based bricks, as well as having good thermal shock resistance compared to fireclay bricks or bricks based on fused or sintered alumina," Walter Hammer, head of purchasing raw materials at Austria-based refractory firm RHI-AG, told IM.
"In the last three years, andalusite demand grew in Asia thanks to the more intensive use of andalusite into refractory production. We observed also a positive trend in the US following the good health of the economy whereas in Europe the economy is suffering from a slowdown." Rob Bartelink, South African specialist andalusite consultant, told IM that the high alumina and low iron contents of Guadalupito's andalusite make it a very suitable product for refractories and other markets.
