Application

Lanthanum-modified lead zirconate titanate (PLZT) fibers with a diameter of around 300 microns were produced by a thermoplastic processing method.

General description

Zirconium(IV) oxide, also known as zirconia or zirconium dioxide, is a white, crystalline oxide of zirconium. It is a refractory material, meaning it is resistant to high temperatures and has good thermal stability. In powder form, zirconium(IV) oxide has a fine, silky texture and is easy to handle. Zirconium(IV) oxide powder has a number of useful properties that make it attractive for a variety of applications. It is an excellent electrical insulator, with a high melting point and a low thermal expansion coefficient. It is also chemically resistant and has good corrosion resistance. Because of these properties, zirconium(IV) oxide is commonly used in the production of ceramics, abrasives, and refractory materials. It is also used in the manufacture of electronics, as well as in the production of catalysts and coatings.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Zirconium(IV) oxide is a sustainable catalyst valued for its high thermal stability and eco-friendly nature. It efficiently promotes green chemical reactions such as hydrogenation and oxidation with high selectivity, enabling cleaner processes that reduce waste and energy consumption, thus supporting environmentally responsible industrial applications.
