I-Tungsten ineyona ndawo iphezulu yokunyibilika kuzo zonke iintsimbi. Iqondo lokunyibilika kwayo limalunga ne-3,422 ngokukaCelsius (6,192 degrees Fahrenheit). Indawo ye-Tungsten ephezulu yokunyibilika inokubalelwa kwizinto ezininzi eziphambili:

1. Iibhondi zentsimbi ezomeleleyo: Iiathom zeTungsten zenza iibhondi zentsimbi ezomeleleyo kunye nomnye, zenza ulwakhiwo oluzinzileyo noluqilima lwelatisi. Ezi bhondi zentsimbi zomeleleyo zifuna umthamo omkhulu wamandla ukuze ziqhawuke, nto leyo ekhokelela kwindawo ephezulu yokunyibilika kwe-tungsten.

2. Ulungelelwaniso lwe-elektroniki: Ukucwangciswa kwe-elektroniki kwe-tungsten kudlala indima ebalulekileyo kwindawo yayo ephezulu yokunyibilika. I-Tungsten inee-electron ezingama-74 ezicwangciswe kwii-orbitals zayo ze-athomu kwaye inezinga eliphezulu lokuchithwa kwe-electron, okubangela ukuba kubekho i-metal bonding eyomeleleyo kunye namandla aphezulu adibeneyo.

3. Ubunzima beathom ephezulu: ITungsten inobunzima beathom obuphezulu ngokwentelekiso, obunegalelo ekusebenzisaneni kwayo okuqinileyo kwe-interatomic. Inani elikhulu lee-athomu ze-tungsten liphumela kwizinga eliphezulu le-inertia kunye nokuzinza ngaphakathi kwe-crystal lattice, efuna ubuninzi begalelo lamandla ukuphazamisa isakhiwo.

4. Iipropati eziphikisayo: I-Tungsten ihlelwa njengentsimbi ephikisayo kwaye iyaziwa ngokumelana nobushushu obugqwesileyo kunye nokumelana nokunxiba. Iqondo layo eliphezulu lokunyibilika liyimpawu ecacileyo yentsimbi ephikisayo, eyenza ixabiseke kwizicelo kwiindawo eziphezulu zokushisa.

5. I-Crystal Structure: I-Tungsten inomzimba-centered cubic (BCC) isakhiwo sekristale kwiqondo lokushisa, elifaka isandla kwindawo yayo ephezulu yokunyibilika. Ukucwangciswa kwee-athomu kwisakhiwo se-BCC kunika intsebenziswano eyomeleleyo ye-interatomic, ephucula amandla ezinto zokumelana nobushushu obuphezulu.

I-Tungsten ineyona ndawo iphezulu yokunyibilika kuzo zonke iintsimbi ngenxa yokudityaniswa kwayo okumangalisayo kweebhondi zentsimbi ezomeleleyo, ulungelelwaniso lwe-electron, ubunzima beathom, kunye nolwakhiwo lwekristale. Le propati ikhethekileyo yenza i-tungsten ibaluleke kakhulu kwizicelo ezifuna ukuba izinto eziphathekayo zigcine ingqibelelo yesakhiwo kumaqondo obushushu aphezulu kakhulu, njenge-aerospace, uqhagamshelwano lombane kunye nezixhobo zokushisa eziphezulu.

I-Molybdenum inomzimba-centered cubic (BCC) isakhiwo sekristale kwiqondo lokushisa. Kulo lungiselelo, ii-athomu ze-molybdenum zibekwe kwiikona kunye nombindi wetyhubhu, ukudala i-lattice ezinzileyo kwaye ifakwe ngokuqinileyo. Isakhiwo se-crystal ye-BCC ye-Molybdenum inceda ukwandisa amandla ayo, i-ductility kunye nokumelana nokushisa okuphezulu, okwenza kube yinto exabisekileyo kwizinto ezahlukeneyo zoshishino, kubandakanywa i-aerospace, i-furnaces ephezulu kunye nesakhiwo esimelana neemeko ezinzima.
