Zirconium Carbide Powder

(Zirconium Carbide Powder)

Zirconium carbide powder is an important high-temperature structural material. It is a gray metallic transition-metal powder, characterized by high hardness and good thermal resistance. In addition, it is effective at reflecting infrared wavelengths. Therefore, it is suitable for applications in aerospace materials and energy storage.

A variety of processes are employed to transform zirconium carbide precursors into nano ZrC powder. The synthesized powders have a small average crystallite size of 200nm. Moreover, the particle size is controlled and dispersed uniformly. This powder can be used for composite materials and SPS applications.

Several studies were carried out to study the phase transformation and gas release in the system ZrO2-B2O3-C. Thermal analysis and thermogravimetry were carried out to determine the temperature changes in the system. Finally, the powder trajectory and diffraction patterns were investigated. These methods help to determine the lattice parameter and melt degree.

Moreover, the results of these studies showed that the heat capacity of the specimen increases rapidly from room temperature to 300 degC. The heat capacity of the specimen is largely influenced by the Debye temperature. Consequently, the heat capacity of the specimen increases with the rising relative density. However, the activation energy is significantly higher for conventional hot pressing than for SPS.

X-ray diffraction was also carried out. The diffraction pattern of the raw powder was investigated. Additionally, copper was used as the target. Compared with the reference peaks along the diffracted planes, the diffracted pattern of the starting powder was estimated.
