Description
Alumina Sol is stable colloidal suspension of nano alumina particles. It features ultra-low alkali content, fine particle size, uniform dispersion and excellent sintering activity. It is used as binder for low cement / ultra-low cement castables, precast blocks, refractory coatings and kiln furniture. During heating, nano alumina grains sinter and form continuous ceramic bonding. It improves hot strength, thermal shock resistance and slag resistance, without introducing alkali impurities. It is widely applied in steel ladle, tundish and high-temperature industrial furnaces. Custom solid content and particle size are available.
