Active spinel prepared by sintering method has outstanding thermal activity, sintering
ability and high density compared with fused spinel. Active spinel is mainly used as the matrix
of refractory spinel. There is no expanding during the sintering process which helps to realize the highest material density. It has good anti-stripping performance and thermal shock stability.
Active spinel prepared by sintering method is more economic than fused spinel, which
can substitutes fused spinel in many situations.
