Solid aluminium silicate spheres
A solid aluminium silicate sphere is an industrial ceramic product with a spherical shape. It is formed through melting and subsequent condensation in a cooling chamber. The optimal spherical shape is created in the initial seconds in an apparent state of weightlessness. The shape is then maintained by increasing the viscosity during the cooling process.
The spherical particles formed by this process are then classified and refined into homogeneous raw materials for our customers’ use. The material is specifically characterised by low oil absorption values and good processing properties. When used in cement-based systems, solid aluminium silicate spheres also have a hydraulic effect and improve the strength of the finished products. Together with the spherical shape, the high degree of hardness helps to modify surfaces for extreme mechanical demands and stresses.
