Аннотация:
Smelting and sintering of the initial ceramics were performed at the Big Solar Furnace with thermal power of $1000$ kW at $2500$-$2700^{\circ}$С. As the base of some ceramics CaMgSi$_2$О$_6$ or Al$_2$O$_3$ + CaZrO$_3$ were used. The spectrum of the infrared radiation of ceramic coatings changed in depending on the introduced dopant oxides. The ceramics exhibit pulse or pulse - pair infrared (IR) radiation which could be photoluminescence or thermal radiation. The attempt is made to explain pulse radiation supposing the possibility of the presence of the energy barrier on the grain boundary of the ceramics. Many types of narrow range ceramic IR radiators are made and successfully applied in medicine.
Some aspects of the converter of Solar energy into thermal radiation - Solar thermal radiator (STR) are considered.
The efficiency of STR with ceramic coating is considered taking into account the photon thermal conductivity, which takes place when ceramic layer does not absorb thermal radiation of the metal sheet substrate.
Ключевые слова:
ceramic materials, the functional ceramics, activation energy, semiconductors, infrared transformers, impulse systems.
