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 2.8 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.
Recycling of sodium polytungstate. Recovery of sodium polytungstate: The polytungstate solution can be recovered by washing respective particles with distilled or demineralized / deionized water. Rinse samples repeatedly. To filter off the solids from the liquid you should use a funnel with filtration paper.

Jul 08, 2015· At the price of sodium polytungstate, its's much better to spend the money of a good scale and make a simple SG determination rig to use with it. For RI determination, the limiting factor is the RI of the glass from which the refractometer prism is made.
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 polytungstate is also called sodium metatungstate, it has the advantages of high density, ordorless, easy to synthesis and can be recycled, it is largely applied in .
When sodium polytungstate is dissolved in water, it produces a low-viscosity, transparent solution with a density up to 3.0 g/cm³. The density of the solution means that solids can then be separated in it, using the sink-float process, for example.
Sodium Polytungstate is one of numerous organo-metallic compounds sold by American Elements under the trade name AE Organo-Metallics™ for uses requiring non-aqueous solubility such as recent solar energy and water treatment applications. Sodium Polytungstate is generally immediately available in most volumes, including bulk quantities.
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.
Sodium polytungstate is a relatively new agent for the production of heavy liquids, which offers substantial advantages over zinc chloride or highly toxic halogen hydrocarbons in sink-float analyses. It dissolves very well in water and can be configured as a pH-neutral solution. The maximum density of the solution is 3.1 g/cm³ at 25°.
