Diatomite powder, a naturally occurring porous raw material, was used to make ceramic materials with porosity and highstrength. The sintering behavior of the diatomite powder at various sintering temperatures suggests that diatomite monolithswith a high porosity and strength can be prepared at 1100 oC. The compressive strength of the sintered diatomite monolithsincreased as the sintering temperature increased, and the molding pressure of 2MPa and the binder of 18.6 wt.% wereexcellent. When the sintering temperature rises, the diatomite powder is melted, and its pores gradually disappear. SEMimages show that strengthening begins with the formation of inter-particle bonds at a low sintering temperature.
