Platinum otu ọla gụnyere platinum (Pt), rhodium (Rh), palladium (Pd), ruthenium (Ru), osmium (Os), na iridium (Ir), nke bụ nke dị oké ọnụ ahịa ọla dị ka gold (Au) na ọlaọcha (Ag). . Ha nwere njikọ atọm siri ike nke ukwuu, wee si otú ahụ nwee nnukwu ike njikọ interatomic yana njupụta kacha. Nọmba nchikota atomic nke ọla otu platinum niile bụ 6, nke na-ekpebi njirimara anụ ahụ na kemịkal pụrụ iche. Platinum otu ọla nwere nnukwu agbaze, ezigbo ọkụ eletrik na nguzogide corrosion, ike okpomọkụ dị elu na nguzogide okpomọkụ dị elu, yana ezigbo nkwụsi ike okpomọkụ. Njirimara ndị a na-eme ka ha bụrụ ihe dị mkpa maka ụlọ ọrụ ọgbara ọhụrụ na ihe owuwu nke mba, nke a na-ejikarị na ụgbọ elu, ikuku ikuku, rọketi, ike atomiki, teknụzụ microelectronics, kemịkalụ, iko, ọcha gas na ụlọ ọrụ metallurgical, na ọrụ ha na ụlọ ọrụ teknụzụ dị elu na-abawanye.
