  1. Reactive Processing of High Temperature MaterialsWilliam G. Fahrenholtz, University of Missouri-Rolla, DMR 0346800 Recent research at UMR has focused on understanding surface chemical reactions that affect the densification of ceramics. Until recently, ZrB2 and HfB2 could only be densified by the simultaneous application of high temperature (≥2000°C) and pressure (≥30 MPa). Our research has identified additives that react with and remove surface oxide impurities (ZrO2 and B2O3), which has enabled full densification without the application of external pressure. Using a combination of B4C and carbon, ZrB2 has been sintered to >99% density at temperatures as low as 1900°C. In May 2007, the Journal of the American Ceramic Society highlighted UMR’s research on boride-based ceramics with a cover photo and a feature article

  2. Awards ceremony at state finals UMR faculty and Caterpillar employees participating in an “Industry” day at UMR Reactive Processing of High Temperature MaterialsBill Fahrenholtz, University of Missouri-Rolla, DMR 0346800 High temperature materials are a focus for undergraduate professional development activities in the Materials Science and Engineering department at the UMR. During the spring of 2007, two seminar speakers discussed career opportunities and research related to high temperature materials. In addition, several industry days were organized for the undergraduates. For one of them, MSE alumni who work at Caterpillar gave an overview of career opportunities and then met with individual students. These interactions have led to summer internships and full-time positions for UMR students in the area of high temperature materials. The UHTC research group continues to be active in WYSE Academic Challenge, which is a statewide high school math and science competition organized by the PI. Students from the group helped monitor the exams, score the exams, and handout the awards. UMR students also worked with the high school teachers that brought students to the competition. The students presented materials-related demonstrations that the teachers could take back to their classrooms.
