The invention discloses a method for preparing cobalt-based black ceramic pigment by utilizing tannery sludge. Leather industrial waste is employed and comprises the following components, by weight: 40-60% of tannery sludge, 20-30% of iron oxide red, 5% of nickel oxide and 15-20% of cobalt oxide. The tannery sludge is calcined and sieved in a non-oxidizing atmosphere for later use, and then the processed tannery sludge and other components are blended, mixed, calcined and crushed to obtain a product. The invention also discloses black ceramic pigment prepared by the preparation method. The method can be used for preparing the ceramic pigment for the black glaze, wherein the pigment is high in blackness, pure in color and stable.
本发明公开了一种利用制革污泥制备钴系黑色陶瓷色料的方法，采用皮革工业废料，其重量百分比组成为：含制革污泥40~60%、氧化铁红20~30%、氧化镍5%和氧化钴15~20%；将制革污泥在非氧化气氛下进行煅烧及过筛备用，然后与其他组份配料、混合、煅烧及粉碎获得制品。本发明还公开了一种采用该制备方法制备的黑色陶瓷色料。该方法可制备黑度高、呈色纯正、能稳定的黑色釉用陶瓷色料。
