氮化铪的化学式为HfN,它是一种高熔点(3310℃)、高硬度、耐磨、抗氧化的新型硬质材料,且非常稳定。 氮化铪不但在耐磨、抗氧化、抗腐蚀及导电性能等方面优于纯金属铪,而且具有较高的超导临界温度,很有可能成为很好的超导体,具有很高的使用价值。 Density 13800 kg/m-3 Solubility in H2O N/A Exact Mass 299.092436...
Novel designed architecture of tailored HfC-HfN solid solution combined with laminated tungsten networks, spark plasma sintered at 2273 K with full density was investigated by multiple-characterizations in as-sintered and ablated states. The pristine substrate is composed of HfC0.72N0.28 solid solution...
The electronic energy-band structures for beta-ZrNCl and beta-HfNCl, which can be superconducting by intercalation, have been calculated by using the scalar-relativistic full-potential linearized augmented-plane-wave method within the local-density approximation. For beta-ZrNCl, we have calculated the...

Hafnium carbonitrideOxidation resistanceSilicon carbideSpark plasma sintering? 2022 Elsevier Ltd and Techna Group S.r.l.The oxidation resistance of the hafnium carbonitride Hf(C,N), HfCN+10 wt% SiC and HfCN+20 wt% SiC ceramics were investigated using thermogravimetric analysis (TGA) and static ...
Silicon carbonitrideOxidationAblationSelf-healingThe oxide scales of hafnium carbide (HfC) typically exhibit a porous structure after oxidation/ablation due to the release of gas oxidation products, which allows oxygen penetration to promote the rapid oxidation of the HfC matrices. Here, we report that...
The nonstoichiometric hafnium carbonitride was then consolidated under a constant pressure of 50 MPa at a temperature of 2000 掳C and a dwelling time of 10 min, through spark plasma sintering. The obtained bulk ceramic material had a theoretical material density of 98%, Vickers hardness of 21.3...
