Abstract:

The work deals with the highly relevant problem, such as creation of sandwich-type composite high-temperature (1000-1150C) experimental samples, which in turn allows to design and manufacture high-temperature energy-efficient thermal equipment such as stoves, dryers and more. The technology of making sandwich-type high temperature, heat insulating materials (HTHIM) working at1150C has been developed, for which the authors used local raw materials based on (foamed perlite and clays), liquid glass,(HTHIM) based on orthophosphoric sandwich panels. The results showed that sandwich type ceramic-perlite-phosphate type of insulation materials can be used to manufacture high-temperature equipment, which are composed of low cost local raw materials, are lighter, more durable, relatively cheap and quite rightly fits into 1000-1150C operationalconditions of furnaces and other equipment.
