On factors affecting the degradation of BaSO4 powders' optical properties under the action of the solar spectrum quanta

Статья в журнале

It has been established that optical properties of BaSO4 powder undergo significant degradation under the action of the solar-spectrum simulating xenon lamp radiation. The cause of such degradation is the presence of intrinsic defects that absorb the solar spectrum quanta with the energy lower than the width of BaSO4 band gap. Preheating at 400 °C for 2 h leads to sintering of powder grains and to the removal of the precipitated water decomposition products, which block the defects’ relaxation. Additionally, the heating makes the radiation stability higher.
