alumina mullite refractories prototypal components
Explain the effects of different composition of high
The firing temperature of the high alumina refractory brick depends on the sinterability of the alumina raw material. When using special grade and grade I bauxite clinker (bulk density ≥ 2.80g/cm3) the structure of the raw material is uniform and the impurity content is high so that the green body is easy to be sintered but the firing temperature range is narrow which may cause over
