Rhodium black,Cas No: 7440-16-6, molecular formula: Rh, molecular weight: 102.91, the boiling point: 3727 ℃, melting point 1966 ℃ density: 12.41, rhodium (Rh) content: 99.9% or higher, iron (Fe) content: 0.005%, or less than the surface area: 40 ~ 60 m2/g, particle size: < 10 nm, pure and not visible to the naked eye inclusions and oxidation color. High corrosion resistance, even insoluble in boiling aqua regia. But hydrobromic acid slightly corrodes rhodium, and wet iodine and sodium hypochlorite can also corrode rhodium. It can be used as raw materials for electrical instruments, chemical industry and precision alloy manufacturing. Store at room temperature, dry and airtight.
