A 99.5% alumina composition has been added to Sunrock Ceramics’ family of HPA high-alumina formulations. Called HPA-99, the material is available as heavy-density brick for hot-face linings in reducing atmospheres and other applications requiring high chemical inertness, such as the processing of piezoceramics and phosphors.
The company can also produce HPA-99 in specialty shapes, such as kiln furniture and hearth plates, formed either by pressing or casting. HPA-99 is being introduced to the market after successful field testing for the last 18 months in very demanding temperature and atmosphere applications in the U.S. and Europe.
“The development of HPA-99 is a great addition to the family of high-alumina ceramics we presently make for the powder metallurgy and technical ceramics markets, including HPA for high-temperature kiln furniture and HPA-CG for pusher plates,” said Doug Thurman, president. “HPA-99 is also ideal in other applications where exceedingly high chemical inertness is of critical importance, such as in the firing of piezoceramics.”
