704  Production of fused zirconia
  The production of fused zirconia is the physical and chemical transformation of zircon (ZrSiO4) by:
 (a) the removal of silica (silicon dioxide (SiO2)) using a reductant such as carbon; and
 (b) heating the zircon to its fusion point;
to produce fused zirconia (zirconium dioxide (ZrO2)) that has a concentration of zirconium dioxide (ZrO2) equal to or greater than 96%.
