Cov muaju ntawm cov hlau sulfide yog hexagonal, octahedral, thiab pentagonal dodecahedral. Hexagonal crystals muaj qhov zoo ntawm lawv lub ntsej muag. Qee lub sij hawm, ntau cov khoom siv lead ua sib xyaw ua ke los tsim ntau yam siv lead ua nyuaj. Nws cov xim tuaj yeem yog golden daj, brassy, los yog nrog lub ci daj xim hlau luster. Nws lub ntiajteb txawj nqus yog -. Nws hardness yog -. Nws cov xim streak yog ntsuab-dub. Nws yog nkig thiab yooj yim tawg thaum ntaus, nrog jagged tawg nto. Thaum incinerated, nws tsim ib tug xiav nplaim thiab ib tug pungent sulfur tsw. Hlau sulfide deposits feem ntau tsim endogenously. Tsis tas li ntawd, pyrosulfur deposits tsim los ntawm coal sulfur deposition kuj tseem ceeb. Unsolidified magma tob hauv lub ntiaj teb muaj cov sulfur ntau. Thaum cov magma nkag mus rau hauv lub pob zeb, lub siab txo qis, tso cai rau cov sulfur uas muaj nyob rau hauv cais tawm.
Raws li cov hlau disulfide, cov khoom siv electrode zoo rau cov roj teeb lithium, nws tuaj yeem siv los kho cov sulfur - muaj cov dej khib nyiab los ntawm kev luam ntawv thiab dyeing nroj tsuag. Hlau sulfide tau yooj yim oxidize thiab discolor nyob rau hauv tsawg tshaj li ib hlis vim lub caij ntuj sov kub. Nyob rau lub caij ntuj no, nws lub neej txee yog txwv rau rau lub hlis. Thaum hlau sulfide deteriorates, nws cov kev ua tau zoo yuav raug cuam tshuam. Kev khaws cia thiab ntim cov lus qhia rau hlau sulfide yog raws li nram no: Vim hais tias hlau sulfide yog ob qho tib si txo thiab oxidizing heev, nws cov ntim yuav tsum tau muab kaw thiab tiv thaiv huab cua. Khaws kom deb ntawm lub teeb, noo noo, thiab nag. Tsis txhob khaws cia nrog oxidants, alkalis, los yog cov khoom noj tshuaj kom tsis txhob muaj kev cuam tshuam. Hlau sulfide yuav tsum tau ntim rau hauv polyethylene yas zaj duab xis hnab ntawm qhov tsawg kawg nkaus thickness. Siv lub hnab yas woven raws li lub ntim txheej. Khi lub hnab sab hauv kom nruj nrog nylon hlua ob zaug lossis siv lwm txoj hauv kev los kaw. Khaws rau hauv qhov chaw kaw nrog qhov cua hauv zos. Khaws kom deb ntawm qhov chaw kub thiab qhov hluav taws kub, thiab tsis txhob khaws cia nrog cov tshuaj lom. Npog yog yuav tsum tau thaum lub sij hawm kev thauj mus los ntawm cov khoom hlau sulfide.
