It is known that the cost of natural ceramic raw materials is increasing every year, despite the use of modern automatic equipment, organization and automation of production, which is associated with the field exhaustion. Therefore, the use of cheap industrial waste, corresponding in its chemical and technological qualities to expensive natural analogues, is considered to be promising. The present article explores the spent catalyst of synthetic rubber IM-2201 production and fireclay chips, formed during the repair of linings made from SHA-5 brick. The results of identifying the granulometric composition on a laser diffractometer revealed that IM-2201 in its chemical and granulometric structure of the particles is comparable to its analogues: the white fused alumina and chrome pigment oxide. Differential curves of white fused alumina and chrome pigment oxide have a single maximum with the smooth nature of the excesses, in contrast to multi-component composites wastes studied in the research. The fractional nature of the particle size distribution of the components comprising the IM-2201, containing 4 pronounced fractions, is also established. The number of fractions, their hardness and fire resistance increase with growing particle sizes. The research of fireclay granulometric composition suggests that it can be used as a coarse-grained filler. The results of the present study can serve as the basis for laboratory and industrial tests of the proposed industrial waste, for example, in the technology of investment casting, as a replacement of expensive corundum and aluminosilicate refractory fillers of single forms.
