The sialons are particularly important because they occur as several polymorphs with different crystal structures and a range of. Oxide ceramics 8 0 introduction oxide ceramics single phase or multiphase are commonly understood to be ceramics with a microstructure consisting essentially of simple oxides. The crucible is a yttrium oxide based ceramic coated crucible comprising a crucible comprising a sintered ceramic of 40 60 wt alumina and 40 60 wt aluminosilicate. A yttrium oxide based ceramic coating is on at least a portion of a surface of the crucible wherein the yttrium oxide based ceramic coating comprises a first zone closest to the crucible.
