The ceramic honeycomb is 5 times bigger than ceramic ball in surface area, 4-5 times in heat-transfer capability, but its resistance to air flow is 1/3 of the ceramic ball and depth of heat penetration is very small
Advantages:
high temperature resistance, corrosion resistance, good heat shock stability, high intensity, big heat storage capacity and good heat-conducting property
Refractory Ceramic Honeycomb
