Tungsten Strontium

The physical properties of tungsten strontium as follows: chemical formula: O4SrW, molecular weight: 335.4576, relative density: 6.187, it can decompose in acid, but insoluble in ethanol and other organic solvents. It is stable at room temperature and atmospheric pressure, but to avoid in contact with material, oxide and halogen. Tungsten strontium has some pollution to water, undiluted or large quantities of tungsten strontium can not to reach ground water, water course or sewage system, what’s, more without the relevant government departments permission can not allow material to be released to the surrounding environment. In addition, tungsten strontium has some toxicity and irritation, during the operation to do some protective measures: such as wearing goggles, gloves, and protective clothing. While avoiding eye and skin contact with the product.

Tungsten strontium preparation methods are the following:
1. To obtain it from the alkali metal and tungstate metathesis reaction.
2. Melting tungsten trioxide and metal oxide to produce tungsten strontium.
3. Take it by melting tungsten trioxide and carbonate.
