Effect of the additions of the waste products of rare-earth elements on the properties of mullite-zircon suspensions

Conclusions The effect of the REE compounds on the rheological properties of the mullite-zircon suspensions was studied. The optimum interval of casting was established. The effect of the REE compounds on the sintering process of the mullite-zircon systems was studied. We demonstrated the possibility of decreasing their sintering temperature by 100°C (up to 1450°C) without loss of thermal shock resistance of the products.Translated from Ogneupory, No. 2, pp. 10–13, February, 1987.
