IHafnium tetrachloride, HfCl4, inombolo yeCAS13499-05-3, yikhompawundi efumene ingqalelo ebanzi ngenxa yoluhlu olubanzi lwezicelo. Ikhemikhali icocekile kakhulu, ukusuka kwi-99.9% ukuya kwi-99.99%, kwaye iza ngendlela yomgubo omhlophe kunye nokuhamba kakuhle. Kuyafaneleka ukuba uqaphele ukuba ukucoceka kwale khompawundi kubaluleke kakhulu, kwaye umxholo we-Zr ungaphantsi okanye ulingana ne-1000PPM (Zr ≤ 0.1%). Iinketho eziqhelekileyo nazo ziyafumaneka ukufikelela kumanqanaba e-Zr aphantsi njenge-200ppm.
Enye yosetyenziso oluphambili lwei-hafnium tetrachlorideifana nesandulela sekeramics zobushushu obuphezulu, ngakumbi kwindawo yee-LED ezinamandla aphezulu. Ukucoceka okuphezulu kunye nomgangatho wekhompawundi kuyenza ilungele usetyenziso olunjalo. Ii-ceramics ze-Ultra-high zibaluleke kakhulu ekuveliseni ii-LED eziphezulu zamandla kuba zibonelela ngokuzinza okufunekayo kwe-thermal kunye nokuqina okufunekayo ekusebenzeni ngokufanelekileyo kwezi zixhobo.
Iimpawu ezizodwa zei-hafnium tetrachlorideyenze ibe sisithako esiyimfuneko ekwenziweni kweeseramikhi zobushushu obuphezulu kakhulu. Ukucoceka kwayo okuphezulu, umbala omhlophe kunye nokumanzi okulungileyo kunceda ukuphucula umgangatho opheleleyo weekeramics eziveliswayo. Ukongeza, ukukwazi ukwenza umxholo we-Zr uphucule ngakumbi ukufaneleka kwayo kwiimfuno ezithile zokuvelisa.
