Walnut shell powder was added into the raw materials of ceramics and grinding wheels. Walnut shell occupied a certain space in the green body, and then sintered, leaving pore forming agent to form pores. Porous ceramics and grinding wheels were prepared. The shape and size of walnut shell powder determine the shape and size of pores in porous ceramic materials and grinding wheels. The products are packed in woven bags of 20 or 25 kg, paper bags or container bags
