Heat-Reflecting Ceramic Materials Based on Potassium Polytitanate and Silicon Oxide

Resumo

The possibility of obtaining a porous ceramic composite with a low heat conductivity and high heat reflecting ability based on a mixture of raw materials including potassium polytitanate and different silicon oxide modifications is investigated. It is shown that the introduction of silicon oxide favors the formation of the potassium silicate glass phase acting as a binding agent and promoting the formation of a ceramic composite structure consisting of interwoven high-strength fibrous K₂Ti₆O₁₃ crystals bound by the evenly distributed glass phase.
