Floating bead is a kind of fly ash hollow ball that can float on the water. It is gray-white, thin and hollow, light weight, closed and smooth surface, low thermal conductivity, refractoriness ≥ 1610 ºC, and is an excellent thermal insulation refractory material. It is widely used in the production of lightweight castables and oil drilling. Floating beads have many characteristics such as fine particles, hollow, light weight, high strength, wear resistance, high temperature resistance, heat preservation and insulation, insulation and flame retardant, and are one of the raw materials widely used in the refractory industry.

Characteristics :Fine particles, hollow, light weight, high strength, wear resistance, high temperature resistance, thermal insulation, insulation and flame retardant.
