Amateka ya Tungsten

Tungsten ni ubwoko bwimiti ifite ikimenyetso W kandi ifite numero ya atome ya 74, ishobora no kwitwa wolfram. Tungsten iragoye kuboneka muri kamere nka tungsten yubusa, kandi ihora ishingiye nkibintu hamwe nibindi bintu.

Tungsten ifite ubwoko bubiri bwamabuye y'agaciro. Ni scheelite na wolframite. Izina Wolfram rikomoka ku rya nyuma. Mu kinyejana cya 16, abacukuzi bavuze ko amabuye y'agaciro yakundaga guherekeza amabuye y'agaciro. Kubera ibara ry'umukara no kugaragara k'ubwoya bw'amabuye y'agaciro, abacukuzi bita ubu bwoko bw'amabuye“wolfram”. Iyi myanda mishya yavuzwe bwa mbere muri Georgius Agricola’s igitabo, De Natura Fossilium mu 1546. Scheelite yavumbuwe mu 1750 muri Suwede. Uwa mbere kuyita Tungsten ni Axel Frederik Cronstedt. Tungsten igizwe n'ibice bibiri, tung, bisobanura uburemere muri Suwede, na sten, bisobanura ibuye. Kugeza mu ntangiriro ya 1780, Juan José de D.´Elhuyar yasanze impyisi irimo ibintu bimwe na scheelite. Mu gutangaza Juan na murumuna we, baha iki cyuma gishya izina rishya, wolfram. Nyuma yibyo, abahanga benshi barushijeho gukora ubushakashatsi kuri iki cyuma gishya.

Muri 1847. injeniyeri witwa Robert Oxland yatanze ipatanti ijyanye na tungsten., Iyo ikaba ari intambwe ikomeye iganisha ku nganda.

Mu 1904, itara rya mbere rya tungsten ryarahawe ipatanti, risimbuza vuba ibindi bicuruzwa, nk'amatara ya karuboni idakora neza ku masoko yamurika.

Mu myaka ya za 1920, kugirango habeho gushushanya bipfa gukomera cyane, hafi ya diyama, abantu bakomeje guteza imbere imiterere ya karubide ya sima.

Nyuma y'Intambara ya Kabiri y'Isi Yose, ubukungu bwifashe neza kandi butera imbere. Tungsten karbide nayo iramenyekana cyane nkubwoko bwibikoresho, bishobora gukoreshwa mubihe byinshi.

Mu 1944, K C Li, Perezida wa Wah Chang Corporation muri Amerika, yasohoye ifoto mu kinyamakuru Engineering & Mining Journal yise: "Gukura Imyaka 40 Igiti cya Tungsten (1904-1944)"kwerekana iterambere ryihuse ryibikorwa bitandukanye bya tungsten mubijyanye na metallurgie na chimie.

Kuva icyo gihe, hamwe n’iterambere ry’ubukungu n’umuryango, abantu basabye cyane ibikoresho byabo nibikoresho byabo, bisaba guhora bavugurura ibicuruzwa bya karubide ya tungsten. No muri iki gihe, abantu baracyakora ubushakashatsi no guteza imbere iki cyuma kugirango batange imikorere myiza nuburambe.

Hano ZZBETTER. Niba ushimishijwe nibicuruzwa bya tungsten ukaba ushaka amakuru arambuye, urashobora kutwandikira ukoresheje terefone cyangwa amabaruwa ibumoso, cyangwa UKOHEREZA MAIL US hepfo yurupapuro.
