YuLi Calcia Stabilized Zirconia Bubble is produced by electro fusing special stabilized zirconia.
As lightweight refractory, Yuli Calcia Stabilized Zirconia Bubble is used for production of refractory insulation materials, refractory lightweight bricks, as loose bulk material for the filling of thermal insulation walls, meanwhile YuLi Calcia Stabilized Zirconia Bubble is ideal filler for high-temp. (2200-2400℃)furnace due to its chemically inert, such as induction furnace, nitriding furnace.
