Descriptio
Chromium metallicum imprimis adhibetur in productione mixturarum niccoli, cobalti, aluminii, titanii, resistentiae, corrosioni, ferri, et chalybis inoxidabilis. Duo genera productionis industrialis chromii metallici sunt: unum est chromium thermite, colore argenteo claro, splendore metallico praeditum, Cr98% continens, et secundum usum impuritatum requisita diversa habet; alterum est chromium electrolyticum, forma laminae, superficie fusca obscura, post purificationem hydrogenii superficiem claram praeditum, Cr99% continens.
Lingotae antimonii
Praecipue ut induratior mixturarum metallorum in metallurgia, accumulatoribus, et industria militari adhibetur.
Adhibetur etiam ut materia prima ad productionem oxidi stibii. Lingota stibii etiam in industria typographica typorum mobilium, materia plumbea, involucro funium, stanne et fulcro labili adhibentur.
Applicatio
Materia prima magni momenti est ad productionem mixturarum specialium, supermixturarum niccoli fundatarum pro turbinis aeroplanorum, necnon tegumentorum pro contactibus vacuis, semiconductoribus, fragmentis, productis electronicis praecisionis, materiis opticis summae qualitatis, et cetera, quae late in metallurgia, electronicis, aviatione, aerospatio aliisque campis adhibentur.
