Vismut qotishmalarining xossalari
Jan 15, 2022
Vismut qotishmalari qattiqlashganda qisqarmaslik xususiyatiga ega bo'lib, quyma va bosib chiqarish turi va yuqori aniqlikdagi qoliplar uchun ishlatiladi.
Vismut qotishmalari ko'pincha qotishmalarning kesish ish faoliyatini yaxshilash uchun quyma temir, po'lat va alyuminiy qotishmalarida qo'shimchalar sifatida ishlatiladi. Infraqizil detektorlarni tayyorlash uchun 11% surma bo'lgan vismut qotishmasi ishlatiladi. Selenli rektifikatorlar uchun yordamchi elektrodlar tayyorlash uchun vismut-qalay va vismut-kadmiy qotishmalaridan foydalaniladi.
A magnetometer was fabricated by utilizing the characteristic of bismuth's sharp decrease in resistivity under the action of a magnetic field. Bismuth-manganese alloys can be used as permanent magnet materials. Bismuth has a small thermal neutron absorption cross section, low melting point and high boiling point, and can be used as a heat transfer medium in nuclear reactors.
Vismut telluridi quyosh xujayralari uchun termoelektrik elementlarni tayyorlash uchun keng qo'llaniladi va vismut telluridi kompyuter chiplarining tezligi va samaradorligini sezilarli darajada oshirishi mumkin.
Bismuth-silver-cesium alloy can be used to manufacture photoelectric amplifiers, silver-bismuth sulfide is used to manufacture semiconductor instruments, and bismuth-cadmium thermoelectric elements are used for alarm devices.
