YuLi recycled bubble alumina is produced by recycled raw materials, the melting point is only 1650℃，but it is environmental-friendly products.

As lightweight refractory, Yuli Bubble alumina is used for production of refractory insulation materials, refractory lightweight bricks, as loose bulk material for the filling of thermal insulation walls, meanwhile YuLi bubble alumina is ideal filler for high-temp. (1600-2400℃)furnace due to its chemically inert, such as induction furnace, nitriding furnace.
