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 reduction rate was dramatically enhanced. Additionally, the results showed that ZrB2 products with different particle shapes were prepared by changing the type of molten salt (NaCl, KCl, MgCl2, and CaCl2). However, the particle size of products could no


Properties and classification of graphite

Crystalline graphite ore can also be divided into flake and dense. Flaky graphite ore is well crystallized, with a crystal particle size greater than one μ m. Generally, it is 0.05~1.5mm, and the large one can reach 5~10mm, mainly in an aggregate. High-quality, large-scale Graphite is essential for producing graphene and expanded Graphite. It plays a significant role in the future development of the emerging graphite industry (or the result of products made). Large-scale Graphite is distributed


Zirconium Diboride Ceramics

What is Zirconium Diforide? Zirconium hydroboride The chemical formula for Zirconium diboride is ZrB2. Zirconium Diboride can be described as a type of covalent high refractory ceramic having a hexagonal crystal. ZrB2 can be used as an ultra-high-temperature ceramic (UHTC), with a melting temperature of 3246°C. Its combination with its low density, 6.09 g/cm 3, and excellent high-temperature stability makes it suitable for high-temperature aerospace applications like rocket propulsion systems
