FIELD: technological processes. ^ SUBSTANCE: inventions relate to material, containing particles of highly porous material of low density, in which pores were at least partially vacuumised and filled with gas again, having low heat conductivity, and produced particles are capsulated with protective and durable coating. Particles of material have porosity of at least 80% and chambers of pores filled with gas have low heat conductivity. These particles are capsulated in protective durable coating, having thickness of not more than 0.5 mm. Thin particles have high porosity, material has low density. These particles in particular are used as durable heat insulation material. ^ EFFECT: provision of insulation in shape of discrete units, ie highly porous particles, material of low density, having low heat conductivity and forming durable wear resistant extremely fine coating. ^ 20 cl, 1 dwg |
