Effect of SiO2 Particle Size on the Reaction between ZrB2 and SiO2 in Air
Source abstract
Abstract
The heat resistance of ZrB2-based composites is shown to depend on the dispersion medium in which the slip-cast bodies were prepared: silica sol ensures the best heat resistance. Heat treatment of ZrB2–SiO2 materials in air at temperatures of up to 1400°C leads to the formation of a borosilicate glass melt containing crystalline particles of ZrB2 , SiO2 , and reaction products. Chemical analysis of heat-treated samples demonstrates that the SiO2 particle size has no effect on this process.
