Zirconia ceramic rods, as the core parts in the power and chemical industries, have abrasion resistance, corrosion resistance, high temperature resistance and impact resistance. The service life is 5-10 times longer than that of alternative products of the same nature. Zirconia ceramic rods are formed by isostatic pressing process and unique design methods, which can be formed by dry forming or steel mould pressing. These two compression molding methods are widely used in the field of zirconia ceramics, and the zirconia ceramics produced by these two methods are extremely dense. The ceramic rod itself has anti-sulfur corrosion performance, and effectively blocks the direct contact between sulfur and the economizer tube, so it is anti-wear and anti-corrosion.
