Making zirconia refractories for lining furnaces producing fused quartz

Properties of CaO-stabilized blocks of electrofired ZrO2 and products based on these blocks

“…The stabilization is effected in an electric-arc furnace by firing the material into a block [3,4].The published literature contains virtually no data on the effect of the concentration of stabilizing additive on the macro-or microstructure of the block after cooling; on its density; on its strength; or on its thermal-shock resistance. Moreover, these properties may be decisive in the case of milling the fired material and for the properties of the product manufactured from this material In order to study these properties we fired blocks from ZrO 2 stabilized by various amounts of CaO and also without any additive.…”
