Development And Characterization Of Ultra Low Cement Castable Cordierites By Thixotropic Properties Mixtures
The main target in this investigation was to take advantage of the reology properties of the tixotropic mixes in Ultra Low Cement Castables (ULCC).The cordierite phase in refractory mix can be obtained using raw materials with magnesium oxide in its composition,such as,Mg(OH)2 or H2Mg3(SiO3)4 (Talc mineral),with a content of 63.5% SiO2,31.7% MgO and 4.8% H2O.In this investigation,as magnesium source,a commercial calcined magnesite with 90% MgO was used.This mineral was selected instead of Talc mineral,because this last contains more impurities in its composition that tend to form more amounts of liquid phases with low fusion points.For this work two different ULCC mixes were designed.These were fired at 1260 ℃,the cordierite phase was quantified in each mix.
