Walnut Shell Pore-forming Agent

The porous ceramics were prepared by adding walnut shell grit into ceramic ingredients, using walnut shell to occupy a certain space in the green body, then sintering, leaving the pore forming agent to form pores. The shape and size of walnut shell particles determine the shape and size of pores in porous ceramic materials. The products are packed in woven bags of 20 or 25 kg, paper bags or container bags
