Ibisobanuro ku bicuruzwa

Hafnium diboride ni ubwoko bwimyenda ya kirisiti kandi ifite urumuri rwinshi, hamwe n’amashanyarazi menshi hamwe n’imiti ihamye. Byongeye kandi, ntibishobora gukoreshwa hamwe na reagent zose (usibye Hf) mubushyuhe bwo murugo. Nubwoko bwibintu bishya byubwoko bwa ceramic hamwe nubushyuhe bwo hejuru bukora neza nko gushonga-hejuru, ubushyuhe bwo hejuru bwumuriro, kutagira ubumara, nibindi, bikoreshwa cyane mubice nka ceramika yubushyuhe bwo hejuru cyane, indege yihuta yizuru hamwe nindege, nibindi.

Gusaba

Hafnium diboride ni umukara-umukara metallic luster kristal ifite imiterere ya kirisiti ni sisitemu ya mpandeshatu. Nkibikoresho byiza cyane byubushyuhe bwa ceramic, hafnium diboride (HfB2) ifite aho ishonga cyane (3380 ℃), ikoreshwa kenshi mubikoresho birwanya anti-ablasi mubidukikije bwa okiside yubushyuhe bwo hejuru kandi ifite ibiranga ubukana bwinshi, modulus nyinshi, ubushyuhe bwinshi nubushyuhe bukabije. Ikoreshwa cyane mubitambara bidashobora kwambara, ibikoresho bivunika, ibikoresho byo gutema hamwe na sisitemu yo gukingira ikirere hamwe nizindi nzego.
