Effect of Nanodispersed Alumina on the Mechanical and Physical Properties of Technical Ceramics
摘要
This study developed technical ceramics for grinding media and examined how a dispersed oxide affects its key properties. The alumina-containing component used was waste catalyst from the gas processing industry. Nanodispersed aluminum oxide was synthesized from chemical reagents via the citrate sol-gel method. The results show that adding 3 wt.% of nanodispersed alumina (over 100 wt.% of the total mass leads) improves abrasion, acid resistance, and mechanical strength of technical ceramics.
