Zincum

Zincum (-i, n.) est elementum metallicum cum numero atomico 30 et symbolo Zn quod est metallum transitionis. Miscebatur cum cupro ut creetur orichalcum in temporibus Romanorum et tractabatur in India ab anno 1200. Metallum purum Europae ante finem saeculi 16mi non agnoscebatur. Tractatio zinci non coepta est ante finem saeculi 17mi. Zincum est utile illinamentum ad impediendum chalybis corrosioni. Accumulatra interdum zinco usurpantur, et orichalcum ex zinco cuproque fit. Zincum extrahitur de sphalerita.

Zincum est minerale vitale, necessarium ad omnes vitae formas sustinendas. Enzymata illa habentia atomum zinci in medio reactivo sunt communia in biochemia. Exemplum est dehydrogenasium alcoholis. Consumptio magnae copiae zinci potest efficere ataxiam, fatigationem, et defectus cupri.

Naturalia

Zincum in sua forma pura est solida, colore pallido cano

Zincum est lucidum diamagneticum metallum. Color zinci inter album canumque alternat.

Metallum est durum fragileque in temperaturis plurimis, sed ductile inter 100 et 150 gradus Celsii fit. Super 200 gradus Celsii, metallum fragile fit, et verberando potest pulverari. Zincum est aequus electricitatis conductor. Id habet fere humilia puncta fusionis ebullationisque metallo. Habet punctum fusionis in 420 gradibus Celsii et punctum ebullationis in 900 gradibus Celsii.

Multae temperationes zincum continent, praesertim orichalcum, temperatio zinci cuprique. Alia metalla quae temperationes cum zinco creant sunt aluminium, stibium, bismuthum, aurum, ferrum, plumbum, hydrargyrum, argentum, stannum, magnesium, cobaltum, niccolum, tellurium natriumque. Dum neque zincum neque zirconium sunt ferromagneticum temperatio ZrZn₂ ferromagnetismum sub 35 gradus Kelvinis ostendit.

Incidentia

Zincum consistit in septuaginta quinque partibus per millionem crustae Terrae.
