Abstract (en)
[origin: WO9932417A1] The present invention discloses a dense refractory material, which includes a spinel matrix and a micro-crack initiating phase dispersed in the matrix. The micro-crack initiating material introduces micro-cracks into the refractory material, which inhibits catastrophic failure as a result of the effects of thermal shock. A method of manufacturing a dense refractory material which includes the steps of mixing precursor oxides for a spinel material, calcining the material, forming the spinel material into a green form of the product and firing the green form to produce the final form is also disclosed.
