Floating beads are a kind of fly ash hollow spheres that can float on the surface of water. They are grayish white, thin and hollow, and light in weight. The bulk density is 720kg/m3 (heavy), 418.8kg/m3 (light), and the particle size is about 0.1. Millimeter, the surface is closed and smooth, the thermal conductivity is small, the refractoriness is ≥1610 °C, it is an excellent thermal insulation refractory material, widely used in the production of light castables and oil drilling. The chemical composition of the floating beads is mainly composed of silica and alumina, and has various characteristics such as fine particles, hollow, light weight, high strength, wear resistance, high temperature resistance, thermal insulation, insulation and flame retardancy. One of the raw materials for the refractory industry.
