Magnesium diboride ndi gulu la ayoni, lomwe lili ndi mawonekedwe a kristalo a hexagonal.Magnesium diboride pa kutentha kwathunthu pang'ono 40K (yofanana ndi -233 ℃) idzasinthidwa kukhala superconductor.Ndipo kutentha kwake kwenikweni ndi 20 ~ 30K.Kuti tifike kutentha kumeneku, titha kugwiritsa ntchito neon yamadzimadzi, haidrojeni yamadzimadzi kapena firiji yotsekeka kuti titsirize kuziziritsa.Poyerekeza ndi makampani amakono omwe amagwiritsa ntchito helium yamadzimadzi kuziziritsa niobium alloy (4K), njirazi ndizosavuta komanso zachuma.Kamodzi ndi doped ndi carbon kapena zonyansa zina, magnesium diboride mu mphamvu maginito, kapena pali podutsa panopa, luso kusunga superconducting ndi monga niobium aloyi, kapena bwino.

Service titha kupereka
1) Mgwirizano wovomerezeka ukhoza kusainidwa
2) Mgwirizano wachinsinsi ukhoza kusainidwa
3) Chitsimikizo chobwezera ndalama masiku asanu ndi awiri
Chofunika kwambiri: sitingapereke mankhwala okha, koma ntchito yothetsera teknoloji!
Ndife opanga, fakitale yathu ili ku Shandong, koma titha kukupatsirani ntchito imodzi yokha!
T/T(telex transfer), Western Union, MoneyGram, BTC(bitcoin), etc.
≤25kg: mkati mwa masiku atatu ogwira ntchito mutalandira malipiro.＞25kg: sabata imodzi
Zilipo, titha kupereka zitsanzo zazing'ono zaulere pazowunikira zabwino!
1kg pa thumba fpr zitsanzo, 25kg kapena 50kg pa ng'oma, kapena monga mungafunire.
Sungani chidebecho chotsekedwa mwamphamvu pamalo owuma, ozizira komanso olowera mpweya wabwino.
