Resumo

OF SILICA REFRACTORY.The characterization of rice husk ash, a deriving byproduct of the burning of the rice husk during the rice processing is the object of this study.This byproduct, for being rich in silica, can be an important raw material for the production of siliceous ceramics, such as thermal insulators and refractory.A combination of surface analysis, thermal analysis and microscopy analysis techniques was used for the characterization.The characterized by-product presented as main component the silica, under amorphous form, with a maximum content of alkalis around 1%, features that become it potentially interesting for the production of ceramic materials.
