Preparation of zirconium diboride by reduction of zirconia with calcium hexaboride
Zirconium diboride (ZrB2) is a typical ultra-high-temperature ceramic material (UHTC). In this work, the preparation of ZrB2 by reducing zirconia (ZrO2) with calcium hexaboride (CaB6) was studied in detail. With the assistance of molten salt, the red...…
