Experimental Study on the Preparation of Porous Ceramic with Vanadium Tailings by Casting Method

Vanadium slag can be utilized as the main raw material,binder,clay,water reducing agent and pore forming agent has been added for,preparing vanadium slag porous ceramics via injection molding process. The obtainedporous ceramic filter can be used in chemical industry,furnace insulation and building decoration industry. In this paper the effect of the calcination temperature,the binder content,the heat preservation time,the clay content,the pore forming agent content,and the effect of pore forming agent on the properties of porous ceramics were investigated. It is found out that combined selection of aluminate cement as binder with~6% addition,calcination temperature of 1 050 ℃,and holding period of 4~6 h,10% clay and 100 mL/150 g raw material of pore forming agent,the satisfied porous ceramic can be obtained.
