alumina ceramic beads for flexible pad heater/technical ceramic/ceramic beads/alumina ceramic
the widest range of ceramic beads for heat treatment. Our 95% Alumina Ceramic Beads is manufactured by dry press method and sintered at temperature upto 1650°C. All the material is prepared by itself. The production is under careful material selection of high grade alumina spray drying granulation from what we call calcined alumina, thus the quality stability is maximally ensured. It enjoys high temperature resistance, excellent insulating property, and efficient thermal conductivity and heat transfer. Thanks to its property, the ceramic beads is widely used as components of flexible ceramic heating pad and channel heaters at operation of pre and postweld heat treatment; welding process, stress-relieving, ship-building, o
