Will DC electric fields transform ceramics shaping, manufacturing?

By / April 7, 2010

According to a paper just published in Philosophy Magazine, researchers at North Carolina State University, who have been playing around with how ceramic materials behave in the presence of DC electric fields, apparently think they may have discovered an approach that could “revolutionize” ceramics manufacturing. At a minimum, they say that using a modest electric…

The Emergence of Intergranular Precipitates in TiO2-Doped alpha-Al2O3 Ceramics

By / January 28, 2010

Volume 93 Issue 2, Pages 326 – 329 Pengxiang Qian, Hui Gu, Miaofang ChiPublished Online: Nov 23 2009 6:57PMDOI: 10.1111/j.1551-2916.2009.03410.x ABSTRACT The minor phase accumulated at intergranular regions in ceramics is usually associated with the global doping level of additives; however, such simplification often undermines the local variation in liquid composition that leads to the…
