Effect of Nano-Oxides on Sintering and Crystallization of Fused Quartz Ceramic Materials

Abstract:

Fused quartz ceramic was prepared in air atmosphere at 1300°C, 1350°C and 1400°C for 1h with fused quartz powder as raw materials (size<0.06mm) and with nano-Cu2O or nano-ZrO2 as additives (size<0.1μm). The effect of nano-Cu2O and nano-ZrO2 (size<0.1μm) on crystallization and sintering of the fused quartz ceramic materials were researched by measurements of apparent porosity, bending strength and thermal expansion rate, and analyses of XRD and SEM. The results showed that nano-Cu2O had detrimental effect on sintering and promoted crystallization of fused quartz, and nano-ZrO2 had better facilitating effect on sintering and better effect of inhibiting crystallization of fused quartz. So, samples with nano-ZrO2 had lower apparent porosity and higher bending strength and more compact microstructure and least thermal expansion rate.
