A Experiment To Tungsten Carbide
【Chinatungsten Online News Net- Tungsten News】
The conductance changes of tungsten carbide in water were investigated in order to study the extent of its oxidation and dissolution by Conductivity Meter. The conductances of different suspension were determined as the changes of concentration, temperature, immersion time and pH values with time were measured. Simultaneously, different aqueous media impacting on oxidation and dissolution of tungsten carbide powder was also studied. The experimental data show that conductance changes results from the oxidation and dissolution oftungsten carbide in water. Owing to pH values in different suspension change significantly, There may be formed tungstate ions and dissociated the proton dissociation at the same time.
