Tungsten trioxide (WO3) can be reduced by reacting with basic sulfides. Basic sulfides such as sodium sulfide (Na2S) and potassium sulfide (K2S) can react with tungsten trioxide under appropriate conditions to reduce it to metal tungsten. Here is an example reaction equation:
WO3 + 3Na2S → W + 3Na2SO4
or
WO3 + 3K2S → W + 3K2SO4
In the above reaction, tungsten trioxide is reduced to metal tungsten by basic sulfide, and the corresponding sulfate (such as sodium sulfate or potassium sulfate) is formed at the same time. The reaction usually needs to be carried out in a high temperature environment, usually in the temperature range of 600°C to 900°C. The reaction temperature and time can be adjusted according to the specific reaction conditions and the desired degree of reduction. During the reduction of tungsten trioxide basic sulfide, attention should be paid to safe operation and control of reaction conditions to ensure that the reaction is carried out under appropriate temperature and atmosphere conditions. In addition, by-products such as sulfates may be produced during the reaction, which need to be properly handled and disposed of. This basic sulfide reduction method has certain application value in the preparation of metallic tungsten materials and some related synthetic and catalytic applications. When carrying out this reaction, please refer to the relevant chemical literature or professional information to understand the specific operating conditions and experimental techniques.
