Properties of Silicon Slag
Silicon slag is a white solid substance separated from the overdesilication operation. Because it contains alumina and alkali, it is usually returned to be mixed into raw meal.
Silicon slag is a water-bearing mixture of zircon sand obtained by alkali melting, acid leaching and water solution.
The colloidal polymer with high quantity has a light yellow-green appearance, spongy shape, strong adsorbability and complex structure. The main components are silicic acid and water, which are acidic after water
immersion, with pH < 1 and solid content about 20%. Due to the chemical reactions occurring in the production process, the silicic acid products such as metasilicic acid, orthosilicic acid, di-metasilicic acid, tri-orthosilicic acid, sodium silicate, unreacted zirconium sand and zirconium oxychloride in the silica slag are still unclear in their structure. Influenced by intermittent alkali fusion operation, different particle size composition of zircon sand and different decomposition rate of zircon sand, the neutral content fluctuates widely.
