Abstract
Description
technical field
[0001] The invention belongs to the technical field of building materials, and in particular relates to a refractory brick produced from aluminum ash and a preparation process thereof. Background technique
[0002] Aluminum ash is the fly ash formed after the condensation of aluminum-containing gaseous volatiles volatilized from the electrolytic cell during the production of electrolytic aluminum. It contains a large amount of aluminum oxide (60-75%), aluminum nitride, silicon oxide, calcium oxide, and a small amount of metal. Aluminum, and a small amount of fluorosilicate, etc. At present, aluminum ash is defined as hazardous waste. Aluminum ash in the electrolytic aluminum industry has become an environmental protection problem that restricts the development of the industry. If aluminum ash is not resolved, it will directly affect the sustainable development of the electrolytic aluminum industry. Aluminum ash is defined as dangerous waste mainly because it...
