Alumina slurry for nitrogen-oxygen sensor and preparation method of alumina slurry
The invention discloses an alumina slurry for a nitrogen-oxygen sensor and a preparation method of the alumina slurry. A wet ball milling process is adopted, alumina powder, a dispersant and a solvent are mixed, zirconium balls are added for ball milling, then filtering, drying and sieving are carried out, the obtained alumina powder is mixed with an organic carrier, and rolling is carried out to obtain the alumina slurry. The obtained slurry is good in fineness, particles cannot be marked on an F.O.G scraper fineness meter, the slurry can adapt to 325-mesh silk-screen printing, the powder falling phenomenon is effectively reduced, operation is easy, and large-scale production is easy.
本发明公开一种用于氮氧传感器的氧化铝浆料及其制备方法，采用湿法球磨工艺，将氧化铝粉体、分散剂、溶剂混合，并加入锆球球磨，然后过滤、烘干、过筛将得到的氧化铝粉体与有机载体混合、轧制得到所述氧化铝浆料。所得浆料细度良好，在F.O.G刮板细度计看不到颗粒划线，且可以适应325目丝网印刷，有效减少脱粉现象，操作简单，易于大批量生产。
