With one of the largest material and process portfolios in the industry, CoorsTek is the leader in technical ceramics manufacturing. Our extensive material portfolio allows us the unique ability to offer a wide range of material property combinations and the ability to solve complex engineering challenges.

Starting with our customers’ component design or particular application need, we select the optimal material from over 400 proprietary material formulations. Our engineers then work to select the ideal forming, firing, and finishing methods to ensure an optimal end product.

Why Ceramics?

Technical ceramics are an important part of our daily lives. From the sensors in our cars to hip implant components to the semiconductor manufacturing process, ceramics do what plastics, metals, and other materials cannot. 

But what are ceramics? They're not just used in pottery. Ceramics are hard inorganic, nonmetallic materials with an impressive capability to hold their properties in extreme environments requiring excellent mechanical, chemical, electrical, and thermal wear resistances. Other materials may excel in one area, but advanced technical ceramics offer exceptional versatility, with material properties that can be manipulated to perform in a specified application.
