Diatomite wet foams were stabilized by diatomite particles that were rendered partially hydrophobic by hexylamine, dried, and then sintered. The particle-stabilized diatomite foam contained primary pores with a size of 50 to 200¯m, formed by particles irreversibly adsorbed at liquidgas interfaces, and secondary pores with a size of about 3¯m, induced by both its irregular particle shapes and inherent pores. In this study, we described a method of preparing diatomite foam with a bimodal pore
