Kedu ígwè nwere ebe mgbaze kachasị elu na gịnị kpatara?

Tungsten nwere ebe mgbaze kachasị elu nke ọla niile. Ebe mgbaze ya dị ihe dịka 3,422 degrees Celsius (n'ogo 6,192 Fahrenheit). Enwere ike ịpụta ebe mgbaze Tungsten dị n'ọtụtụ isi ihe:

1. Strong dara agbụ: Tungsten atọm na-etolite ike dara agbụ na onye ọ bụla ọzọ, akpụ a ukwuu kwụsiri ike na ike lattice Ọdịdị. Njikọ ọla ndị a siri ike chọrọ nnukwu ume iji mebie, na-ebute ebe mgbaze dị elu nke tungsten.

2. Nhazi eletrọnịkị: Nhazi eletrọnịkị nke tungsten na-arụ ọrụ dị mkpa na ebe mgbaze ya dị elu. Tungsten nwere eletrọn 74 ahaziri n'ime orbitals atomic ya ma nwee ogo dị elu nke delocalization eletrọn, na-ebute njikọta ọla siri ike na ike jikọtara ọnụ.

3. Akwa atomic mass: Tungsten nwere oke atomic dị elu, nke na-enye aka na mmekọrịta ya na interatomic siri ike. Ọnụ ọgụgụ dị ukwuu nke atom tungsten na-eme ka ọkwa dị elu nke inertia na nkwụsi ike n'ime kristal kristal, na-achọ nnukwu ntinye ike iji mebie nhazi ahụ.

4. Ngwongwo ndị na-emegharị emegharị: A na-ekewa Tungsten dị ka metal refractory ma mara ya maka oke okpomọkụ na-eguzogide ma na-eyi nguzogide. Ebe mgbaze ya dị elu bụ njirimara na-akọwapụta ọla ndị na-emegharị emegharị, na-eme ka ọ baa uru maka ngwa na gburugburu okpomọkụ dị elu.

5. Crystal Structure: Tungsten nwere ihe owuwu kristal na-ahụ maka cubic (BCC) na ụlọ okpomọkụ, nke na-enye aka na ebe mgbaze ya dị elu. Nhazi nke atọm na usoro BCC na-enye mmekọrịta mmekọrịta siri ike, na-eme ka ihe onwunwe nwee ike iguzogide okpomọkụ dị elu.

Tungsten nwere ebe mgbaze kachasị elu nke ọla niile n'ihi nchikota ya dị ịrịba ama nke njikọ ọla siri ike, nhazi eletrọn, oke atomic na nhazi kristal. Ngwongwo a pụrụ iche na-eme ka tungsten dị mkpa maka ngwa ndị chọrọ ihe ahụ iji nọgide na-eguzosi ike n'ezi ihe na oke okpomọkụ, dị ka ikuku ikuku, kọntaktị eletrik na ihe ọkụ ọkụ ọkụ.

Molybdenum nwere ihe owuwu kristal nke dabere na cubic (BCC) n'ime ụlọ okpomọkụ. N'ime nhazi a, atom molybdenum dị na nkuku na etiti cube ahụ, na-eme ka usoro lattice kwụsie ike na nke siri ike. Ọdịdị kristal BCC nke Molybdenum na-enyere aka ịbawanye ike ya, ductility na nguzogide okpomọkụ dị elu, na-eme ka ọ bụrụ ihe bara uru maka ngwa ọrụ mmepụta ihe dị iche iche, gụnyere ikuku ikuku, ọkụ ọkụ dị elu na ihe nhazi nke na-eguzogide ọnọdụ dị oke egwu.
