Porous Ceramic Carrier

Adherence of functional microorganisms, Porous expandable ceramic carrier

Summary

It is a ceramic carrier with excellent physical and chemical properties as a porous material that is calcined and expanded at 1150~1200℃ by uniformly mixing natural organic matter with inorganic minerals.
