Drift bead is a type of fly ash hollow ball that can float on the water surface. It is gray white in color, with thin and hollow walls, and a very light weight. The unit weight is 720kg/m3 (heavy), 418.8kg/m3 (light), and the particle size is about 0.1mm. The surface is closed and smooth, with low thermal conductivity and a fire resistance of ≥ 1610 ℃. It is an excellent temperature retaining refractory material, widely used in the production of lightweight castables and oil drilling. The chemical composition of floating beads is mainly composed of silicon dioxide and aluminum oxide, which have various characteristics such as fine particle size, hollow, light weight, high strength, wear resistance, high temperature resistance, insulation and flame retardancy. They are widely used as raw materials in the refractory industry.
