In our experience, SPT (sodium polytungstate) and LMT (lithium metatungstate) are not used by many mineral labs which need a heavy liquid with a density of g/mL or more, because their solutions at these densities are too viscous. Typically the viscosity of these liquids is greater than 25 cP, or more than 25 times the viscosity of water.

Do not mix sodium polytungstate solutions with LST Fastfloat because the two materials are not compatible: a mixture of the two will not reach high densities. LST Fastfloat is not compatible with alkaline chemicals or alkaline solids such as lime. Only deionised water should be used for diluting LST Fastfloat heavy liquid.
Sodium metatungstate is the inorganic compound with the formula Na 6 [H 2 W 12 O 40], sometimes written 3Na 2 WO 4 ·9WO 3 ·H 2 O. It also called as sodium polytungstate (SPT). This salt has been used in the manufacture of dense aqueous solutions. Sodium metatungstate exists as white solid.
