Chemically Pure Sodium Tungstate 1,043

Chemically pure sodium tungstate is a good inhibitor for carbon steel in simulated seawater, and the inhibition efficiency increased with the increase of inhibitor concentration, and the adsorption of sodium tungstate onto the surface of carbon steel followed the amended Langmuir adsorption isotherm equation. Composite of sodium tungstate and SLS has better corrosion performance than that of sodium tungstate alone, which shows excellent synergistic effect. Compound inhibitor has higher efficiency, with lower Tafel slope on the cathode and anode and…

High Purity Sodium Tungstate Dihydrate 1,108

High purity sodium tungstate dihydrate is a colorless or white crystalline powder that can be decomposed by strong acids into tungstic acid (water-insoluble). It is easily weathered in dry air. And it is stable in air, but heated to lose crystal water into anhydrous salt at 100°C. Besides, it is soluble in water and insoluble in ethanol. High purity sodium tungstate dihydrate can be applied for the preparation of tungstic acid, and tungstate, etc. And it can also be used…

99.5% Tungstic Acid 714

99.5% tungstic acid may be prepared by “dissociation-slurrying-acid decomposition” process. This process uses less raw materials and auxiliary materials. And it is easy to operate. So, it is cost-saving and time-saving. Some people have conducted experiments on acid decomposition of tungstic acid, acid decomposition of ammonium paratungstate (APT), and acid decomposition of CaWO4 to make tungstic acid. The first two methods have been found to be slow to decompose. As the decomposition reaction proceeds, the acidity decreases continuously, so that…
