The trend toward thinner, smaller, and higher performance electronic components and the exploding market for videocassette tape and similar products have increased the demand for ultrafine, high-purity powders. Such powders include magnetic coating materials, dielectric ceramic powders, piezoelectric ceramic powders, and semiconductor processing materials. Ultrafine, high-purity powders are also required for pigments, automotive coatings, pharmaceuticals, and foods.
A comparison of zirconia ceramic grinding media
If your grinding operation is like many others in the dry solids industry, you need to produce high-purity powders with narrow particle size distributions while also controlling your operating costs. These requirements are driving the use of low-wear grinding media and mill components made from high-density ceramic materials. After introducing you to basic ceramic grinding media selection factors, this article focuses on zirconia ceramic media: comparing the performance of various types and selecting one for your application.
