Heat Storage Ceramic Ball
Thermal storage ceramic ball:with high strength, well-resistance, large thermal conductivity and good heat storage effect
Thermal storage ceramic ball is specially utilized as the packing in the thermal storage equipment of air separating (The heat exchange medium). It can work within the scope of 0-300 celsius degrees.
Requirement for the outward appearance: The surface is smoothing, and there are not spots, crackles, and the other obvious defects.
