Kumukūʻai o Cerium Boride 99% Min Purity i hana ʻia ma Kina

Kahua noi:

He mea hoʻoheheʻe ʻia ʻo Cerium boride ma ke ʻano he uhi no nā cathodes wela, a i ʻole ka cathode wela i haku ʻia me nā kristal hexaboride cerium.Hoʻohana pinepine ʻia ka Cerium hexaboride (CeB6) a me ka lanthanum hexaboride (LaB6) ma ke ʻano he mau uhi cathode wela o kēia manawa.He haʻahaʻa ka hana o ka Hexaboride, ma kahi o 2.5 eV, a loaʻa iā ia kekahi ʻae ʻana i ka hoʻohaumia cathode.ʻO nā cathodes Cerium boride he haʻahaʻa haʻahaʻa haʻahaʻa ma mua o ka lanthanum boride ma 1700 K, akā lilo lākou i mea like ma 1850 K a ʻoi aku ka kiʻekiʻe o ka evaporation ma luna o kēlā mahana.He 50% ʻoi aku ka lōʻihi o ke ola o nā cathodes Cerium boride ma mua o ka lanthanum boride ma muli o ko lākou kūʻē ʻana i ka pollution carbon kiʻekiʻe.ʻO ka'ōlinolino o ka boride cathode heʻumi manawa o ka tungsten cathode aʻo kona ola he 10-15 manawa o ka tungsten cathode.Ua hōʻike ʻia kekahi mau hoʻokolohua hoʻokolohua ʻoi aku ka hoʻomanawanui ʻana o CeB6 i nā hopena maikaʻi ʻole o ka pollution kalapona ma mua o LaB6.Hoʻohana maʻamau ʻia lākou i, no ka laʻana, electron microscopy, microwave tubes, electron beam etching, electron beam welding, X-ray tubes, a me nā laser electron free.
