ABSTRACT OF THE DISCLOSURE: A thermoinsulating mass comprises from 20 to 50 parts by weight of refractory clay and/or kaolin, from 5 to 30 parts by weight of liquid or solid water- soluble inorganic bond, from 5 to 50 parts by weight of water and from 50 to 180 parts by volume per 100 parts by volume in relation to the remaining mixture, of a burning out substance imbibed with liquid inorganic bond. The burning out substance may be husks of rice, wheat, oats, rye, barley, saw-dust, cellulose pulp or a mixture of any of these. The inorganic bond is a mix- ture of acid metal phosphates or of metal sulphates and phosphates or an organosilicate compound. The ad- vantages of this thermoinsulating refractory mass are the combination of high refractoriness, resp. high working temperature and low thermic conductivity as well as the use of cheap and largely available raw-materials. The thermoinsulating mass is used for insulation of thermic aggregates.
