| Abstract Scope |
Binary and pseudo- binary compounds that appear on the equilibrium phase typically are significantly better studied than those that do not. The advantage of producing non-equilibrium materials could be different and/or better properties than the more common counterparts. Here we discuss strategies for reliably producing relatively large sized samples of oxide and semiconductor material using current activated pressure assisted densification (CAPAD). In one example, we discuss composites composed of cubic (stable) and trigonal (metastable) phases using a combination of high energy ball milling and CAPAD. We present a kinetic study of the densification and cubic to trigonal phase transformation. In the oxide case, we show result of the development of non equilibrium phase content as a result of excellent control of densification vs phase change. In addition, we present transport property and optical measurements to highlight the versatility of eth materials produced. |
