If there is a main component of cenosphere light insulating brick.
Light heat insulation brick with cenosphere composition, material properties will be more high, especially the main properties of thermal conductivity
Before 2003 because the price is cheaper to do so cenosphere light heat insulation brick is generally used zeeospheres. After 2003 basically replaced by fly ash and other lightweight refractory material, but some high-grade light brick or floating beads.
