High Temperature Ceramic-Vermiculite Thermal Insulation with Wollastonite Binder

Ceramic-vermiculite thermal insulation with a wollastonite binder was prepared from chalk, diatomite, and expanded vermiculite by means of solid-phase synthesis of the components. The influence of the granulometric composition of expanded vermiculite and the influence of the composition of the batch on the phase composition and the physicomechanical and thermophysical properties of ceramic materials were studied. The main crystalline phase of the ceramic samples is biotite and wollastonite. The developed ceramic-vermiculite thermal insulation has an apparent density 310 – 510 kg/m3 and can be operated at temperatures up to 1050°C inclusively. The developed materials can be used as fire-resistant thermal insulation for industrial furnaces, equipment, and so on.
