Bakar sulfid

Bakar sulfid opisuje familiju hemijskih hedinjenja i minerala sa formulom Cu_xS_y. Neki bakarni sulfidi su ekonomski važne rude.

Prominentni bakarno sulfidi minerali su Cu₂S (halkocit) i CuS (kovelit). U rudarskoj industriji, minerali bornit ili halkopirit, koji se sastoje od smeše bakarno-gvozdenih sulfida, se često nazivaju "bakarnim sulfidima". U hemiji, "binarni bakarni sulfid" je bilo koje binarno hemijsko jedinjenje elemenata bakra i sumpora. Nezavisno od njihovog izvora, bakar sulfidi široko variraju u njihovom sastavu sa 0.5 ≤ Cu/S ≤ 2, uključujući brojna nestehiometrijska jedinjenja.

Poznati bakar sulfidi

Prirodna mineralna binarna jedinjenja bakra i sumpora su navedena ispod. Verovatno postoje i druga jedinjenja koja još nisu otkrivena. Na primer istraživanja "blaubleibender kovelita" formiranog prirodnim izluživanjem kovelita (CuS) indiciraju da postoje druge metastabilne Cu-S faze koje još nisu okarakterisane.^[1]
