Environment-friendly ceramic and preparation method thereof
The invention discloses an environment-friendly ceramic and a preparation method thereof, and belongs to the field of ceramics, the method comprises the following steps: grinding and mixing kaolin, boric oxide, carbon powder, zirconium, barium carbonate, calcium carbonate, boron, silicon and titanium to obtain a mixture; mixing zinc nitrate, zirconium nitrate and a dispersing agent to obtain a mixed solution; mixing the mixture with the mixed liquid to obtain mixed slurry; preparing the mixed slurry into a blank body; putting the blank body into a sintering furnace, heating to 560-720 DEG C, and treating in a first treatment environment for 1.5-4 hours; the temperature of the sintering furnace is increased to 880-1130 DEG C, and treatment is conducted for 2-5 h in a second treatment environment; the temperature of the sintering furnace is increased to 1280-1420 DEG C, and treatment is conducted for 3-6 h in a third treatment environment; the temperature of the sintering furnace is increased to 1530-1620 DEG C, and treatment is conducted for 1-3 h in a fourth treatment environment; the first treatment environment, the second treatment environment, the third treatment environment and the fourth treatment environment comprise vacuum or inert atmosphere. The sintered ceramic is high in strength and good in wear resistance and corrosion resistance.
本发明公开一种环保陶瓷及其制备方法，属于陶瓷领域，方法包括：将高岭土、氧化硼、碳粉、锆、碳酸钡、碳酸钙、硼、硅、钛研磨混合得混合料；将硝酸锌、硝酸锆与分散剂混合得混合液；将混合料与混合液混合得混合浆料；将混合浆料制成胚体；将胚体放在烧结炉升温至560‑720℃在第一处理环境中处理1.5‑4h；将烧结炉升温至880‑1130℃在第二处理环境中处理2‑5h；将烧结炉升温至1280‑1420℃在第三处理环境中处理3‑6h；将烧结炉升温至1530‑1620℃在第四处理环境中处理1‑3h；第一处理环境、第二处理环境、第三处理环境与第四处理环境包括真空或惰性气氛。烧结陶瓷强度高，耐磨性与耐腐蚀性较好。
