Large amount of abandoned denitration catalysts are produced in China every year

the safety dispose and resource utilization of them becomes urgent. The TiO_2 content in vanadium titanium denitration catalyst is critically high

which could be used as raw material for ceramic preparation to realize high value-added utilization. In this paper

the waste vanadium titanium denitration catalyst from a coal-fired power plant in Baotou was used for raw materials for preparation of titanium base ceramic

and the CuO

borax and Nb_2O_5 were used as admixtures. Through the tests of volume density

water absorption

compressive strength

bending strength

Vickers hardness and leaching rate of toxic elements

the influence of admixtures was studied. The results show that

the CuO doping went against the samples' densification

doping borax with concentration of 2% improved the sample hardness sharply

the 2% Nb_2O_5 doped samples performed the best

of which the leaching rate of toxic elements reached the national standard. The high temperature heated method using waste vanadium titanium denitration catalyst as raw materials has an obvious effect in solidification of the toxic V elements.
