Magnesium diboride ni ionic compound, hamwe na kristu ya mpandeshatu. Magnesium diboride ku bushyuhe bwuzuye gato 40K (bihwanye na -233 ℃) bizahinduka umuyoboro udasanzwe. Kandi ubushyuhe bwacyo bukora ni 20 ~ 30K. Kugirango tugere kuri ubu bushyuhe, dushobora gukoresha amazi ya neon, hydrogène y'amazi cyangwa firigo ifunze-cycle kugirango turangize gukonja. Ugereranije ninganda zubu ukoresheje helium yamazi kugirango ukonje niobium alloy (4K), ubu buryo buroroshye kandi bwubukungu. Iyo bimaze gukopororwa na karubone cyangwa ibindi byanduye, magnesium diboride mumurima wa magneti, cyangwa harikintu cyanyuze, ubushobozi bwo gukomeza imiyoboro irenze urugero niobiyumu ya niobium, cyangwa nibindi byiza.

Serivisi dushobora gutanga
1) Amasezerano asanzwe arashobora gusinywa
2) Amasezerano y'ibanga arashobora gusinywa
3) Ingwate yo gusubizwa iminsi irindwi
Icy'ingenzi: ntabwo dushobora gutanga ibicuruzwa gusa, ahubwo tunatanga serivisi yo gukemura ikoranabuhanga!
Turi ababikora, uruganda rwacu ruherereye i Shandong, ariko turashobora kandi gutanga serivisi imwe yo kugura kubwawe!
T / T (kohereza telex), Western Union, MoneyGram, BTC (bitcoin), nibindi
≤25kg: mugihe cyiminsi itatu yakazi nyuma yo kwishyura. ＞ 25kg: icyumweru kimwe
Iraboneka, turashobora gutanga ingero ntoya kubuntu kubwintego yo gusuzuma ubuziranenge!
1kg kumufuka fpr ntangarugero, 25kg cyangwa 50kg kurugoma, cyangwa nkuko ubisabwa.
Bika kontineri ifunze cyane ahantu humye, hakonje kandi hahumeka neza.
