Microspheres/Cenospheres

DESCRIPTION

MICROSPHERES or CENOSPHERES are spherical alumina-silicate particles filled with nitrogen and carbon dioxide originating as a result of hard coal burning in power stations. The granules (microspheres) transported together with slag to a sedimentation pond flow out over the water surface. Microspheres are scooped from the water surface and they are transferred into a dripping chamber made of tarpaulin to lose excessive water. White microspheres occur naturally less frequent and are mainly used in applications, where high temperature, extreme heat and mechanical resistance are demanded. Also the brightness of particles are important to reflect heat as typical refractory material. Particle size of MICROSPHERES is from 5 to 500 / 300 / 160 micrometers (microns, μm).
