Patent ID: 6887810

Claim:
A process for producing a refractory product or a refractory shaped body, comprising: producing an elasticizer material containing raw materials including Al 2 O 3 , MgO, and an iron compound, said raw materials being fused or sintered to form an elasticizer which is a pleonaste, and/or a spinel of a pleonaste type, a ratio of the iron provided in said elasticizer calculated as Fe 2 O 3 :Al 2 O 3 , ranging from 30:70 to 60:40, said elasticizer being formed to contain from 20 to 60% by mass of MgO, based on Fe 2 O 3 +Al 2 O 3 , said elasticizer being solidified and crushed, and then being prepared by classifying said elasticizer into corresponding grain sizes; and said elasticizer then being mixed with a refractory mineral metal-oxide main component defined as a resistor.
