Das immer größer werdende Umweltbewusstsein in allen Bereichen der Chemie hat zur Folge, dass der Anwenderkreis von Natriumpolywolframat in den . LST Fastfloat has half the viscosity of sodium polytungstate heavy liquids. In this study a new non-toxic alternative, sodium polytungstate, has been compared to bromoform. They are SPT (sodium polytungstate, or sodium metatungstate), and the lithium equivalent LMT which is lithium metatungstate. It brings a number of advantages with it.
