Fusion-Cast Refractories in the High-Zirconia Region of the ZrO2 - SiO2 - Cao System

Refractories and Industrial Ceramics Aims and scope

Abstract

The synthesis and properties of fused materials in the ZrO2 - SiO2 - CaO system (83.1 – 91.7% ZrO2, 0.3 – 9.2% SiO2, and 0.6 – 7.8% CaO) are reported. CaO-assisted stabilization of ZrO2 to yield a cubic modification is reached at a SiO2 concentration of ≤ 4.3%. The arc furnace technology developed can be used to fabricate crucibles, tubes, rings (of diameter 320 mm and height 310 mm), and other shaped components from high-zirconia refractory materials with more than 90% ZrO2.
