Zirconia-containing ceramic balls have very low porosity and are used in bearings. Such ceramic balls have a thermal expansion coefficient of six to nine x 10-6, a value that is comparable to steel. Furthermore, they have a linear expansion coefficient similar to steel. When they are applied to high-speed rotation, zirconia ceramic balls can be subjected to temperatures of over 80deg C.

The global zirconia ceramic ball market is segmented by type, application, and region. The report also provides regional sales data for each of the segmented regions. It also includes regional volume and revenue forecasts by country. This report covers sales data for zirconia ceramic balls across different regions, including North America, Europe, Asia-Pacific, Latin America, Middle East, and Africa.

The electrically conductive inorganic phase can be composed of Hf, Mo, Ti, Zr, or Ta. It may also contain electrically conductive oxides like copper, chromium, or nickel. The electrically conductive oxide phase is typically about ten to eighty percent of the total volume of zirconia ceramic.

Zirconia-containing ceramic balls are manufactured using a variety of processes. The most common one is the uniaxial pressing process. This method can produce green bodies with a diameter of twelve millimeters. Injection molding is another method of producing green bodies. During this process, the green body is subjected to high pressures and temperatures to form the ball.

Another application for zirconia-containing ceramic balls is in check valves. A check valve is a device that comprises a valve body and a ball that limits fluid flow to a single direction. The ball is made of zirconia-containing ceramic and is manufactured using a rolling granulation process. This type of ceramic ball exhibits increased durability and a long life.

The zirconia ceramic ball is also useful in precision equipment. Because of its high wear resistance, it can be used as a ball bearing.
In addition to serving as a rolling element, zirconia balls are used to minimize the variation in pre-load caused by temperature changes.

A zirconia ceramic ball may have a nucleus that is composed of different materials. The nucleus may be made of a different ceramic powder, or may be made of a metal or glass powder. This type of nucleus is unlikely to be an impurity source.
