Preparation of Wear-Resistant Ceramics with Tangshan Ironstone-Tailings

Wear-resistant ceramics were prepared successfully with Tangshan Ironstone-tailings. The effects of additives and sintering temperature on their mechanical property were studied. The erosive wear performance of ceramics was evaluated in liquid-solid flow. The erosive wear mechanism was also analyzed. The results showed that the wear-resistant ceramic prepared at 1200°C using 50wt% Tangshan Ironstone-tailings 10wt%, mild-clay and 40wt% high aluminum fly ash as the starting materials had high strength and good erosive wear resistance. The erosive wear mechanisms were washout particles’ micro-cutting and liquid washing.
