The chemical composition of floating beads is mainly silicon dioxide and aluminum oxide. It has many characteristics such as fine particles, hollow, light weight, high strength, wear resistance, high temperature resistance, thermal insulation and flame retardant. It is widely used in One of the raw materials for the refractory industry.
SiO₂ 56%-62%
Al2O3 33%-38%
Fe2O3 2%-4%
CaO 0.2%-0.4%
MgO 0.8%-1.2%
K2O 0.8%-1.2%
Na2O 0.3%-0.9%

What is the Ceramic Hollow Microspheres ?

u Ceramic Hollow Microspheress are hollow ceramic microspheres found in fly ash, a natural by-product of coal combustion during the generation of electric power.

u Refractoriness of Ceramic Hollow Microspheres is 1610 degree celsius, it’s a excellent light weight insulation thermal refractory material.

u Because of small, light weight, hollow, hight strength, Ceramic Hollow Microspheres are widely used as fillers or functional extenders in the manufacture of plastics, paints, resins etc.

u Cenospheres also provide the advantage of significantly improved flow and workability which are all desirable in a range of applications, such as: Oilwell Cementing, Refractories.

u Cenospheres also provide the advantage of significantly improved flow and workability which are all desirable in a range of applications, such as: Oilwell Cementing, Refractories & Foundries, Cementitious Construction Products, Joint-Compounds, Bitumen Sound-Dampening, Adhesives, and many more.
