Ti-based porcelain made from waste vanadium-titanium denitration catalyst and preparing method thereof
The invention relates to ti-based porcelain made from a waste vanadium-titanium denitration catalyst and a preparing method thereof. The ti-based porcelain is characterized by being prepared from, by mass, 30-80% of waste vanadium-titanium denitration catalyst, 0.22-45% of silicon source powder, 0.06-18% of aluminum source powder, 0.02-9% of burn promoting agent, and 0.1-10% of V element solid solvent. The raw materials are smashed, blended, mixed, molded, dried and calcined to generate the ti-based porcelain. The leaching rate of the V element in the prepared ti-based porcelain product is far lower than the V element content limiting value requirement of the GB26452-2011 vanadium industrial pollutant discharge standard. Secondary pollution of the waste poisonous vanadium-titanium denitration catalyst is completely avoided, and high-value-added resource utilization of the waste poisonous vanadium-titanium denitration catalyst is effectively achieved. The ti-based porcelain is low in cost, excellent in performance, easy to prepare, capable of serving as textile porcelain, building and sanitary porcelain, art porcelain and the like, and broad in market prospects, and the performance index is the same as or higher than that of industrial pure TiO2 porcelain.
