以铬渣为主要原料,配入粘土和长石,研制了一种性能符合国家标准、烧成温度仅为1210℃,红棕色的瓷质装饰砖,所选最优坯料配方中的铬渣利用率达46%,经检测瓷质砖浸出的可溶性六价铬为0.018 mg/kg,远低于国家标准5 mg/kg控制值,实现了对有害固废铬渣的资源化,减量化,无害化处理.

A red brown porcelain tile meeting the international standard was fabricated by sintering chromium salt dreg with clay and feldspar as the additives at 1210 degrees C. The optimal amount of the chromium salt dreg was determined to be 46 wt% in the products. Only 0.018 mg/kg of soluble six-valence chromium was detected in the products which was far less than the value of 5 mg/kg for the national standards. Therefore, the chromium salt dreg can be used as a subst...
