High-temperature thermal insulation materials are widely used in civil engineering as flame retardant materials, as well as in many industries. Rocks and industrial waste are used as raw materials for their production. The article confirms the possibility of using ceramovermiculite and keramoperlite materials on a wollastonite bond as high-temperature thermal insulation. The materials were obtained by firing a charge of chalk, diatomite and heat-resistant filler (expanded perlite, expanded vermiculite). The material of the fired samples with expanded vermiculite consists mainly of the crystalline phase of wollastonite and biotite with a small amount of quartz and ackermanite-helenite. When using expanded perlite as a heat-resistant filler, in addition to the crystalline phase of wollastonite, a small amount of plagioclases is present in the material of the burnt samples, and an amorphous phase also appears. The physicomechanical properties of the charge and the fired samples were determined, and the effect of the apparent density and phase composition of the developed materials on the change in their thermal insulation properties at high temperature was studied. The thermal insulation properties of materials at high temperature were determined by unilateral exposure of the sample to heat flow from the heating chamber of the muffle furnace. Samples from the developed materials have an apparent density from 375 kg/m3 to 630 kg/m3 and compressive strength from 0.95 MPa to 3.25 MPa. The developed keramoperlite materials on a wollastonite bond can be used as high-temperature thermal insulation up to +900 °C, and ceramovermiculite – up to +1050 °C. According to many physico-mechanical and thermophysical properties, the materials obtained are not inferior to known analogues.
