ST. ALBANS, Vt., July 30, 2014 /PRNewswire/ -- In a new white paper, Superior Technical Ceramics (STC) has outlined how Zirconia Toughened Alumina (ZTA) is similar to Yttria-stabilized Tetragonal Zirconia Polycrystal (YTZP) in that it possesses a similar crystal structure that, under applied stress, performs in ways that toughens its overall structure.
When Zirconia particles are added to an alumina matrix, that matrix will change under applied stress from a tetragonal structure to a monoclinic structure. This transformation results in an expansion of the volume, compressing the surrounding crack in the alumina matrix. Like YTZP, this stops the crack and restricts it from growing, resulting in a stronger and tougher material than regular alumina.
"We're always looking for ways to make our parts more versatile and more durable, and more of a value to our customers" notes STC Sales Manager, Simon Doran. "Materials like ZTA allow us to meet engineering challenges across a wide variety of industries that other materials simply cannot match."
The whitepaper goes on to highlight ZTA's performance in hydrothermal conditions and outlines why the material is ideal for applications that call for strength, toughness, chemical inertness and wear resistance.
The white paper is available on Superior Technical Ceramic's website here and should be of interest for anyone looking to engineer impact resistant, wear resistant or chemically inert components.
Superior Technical Ceramics, located in St. Albans Vermont, is a market-leading technical ceramic manufacturing company with more than 116 years of expertise. The firm offers custom engineering services, including prototyping, materials design consulting, and custom manufacturing.
