- Abstract
Selecting talcum powder as the main raw material, porous ceramic heads for copper sulfate reference electrode(CSE) were prepared by adjusting the parameters of raw material size, sintering temperature, binder content, molding pressure and sintering mode. The porosity, pore size, morphology, structure, shrinkage and other performance parameters of the porous ceramic heads were tested and analyzed. Three kinds of porous ceramic heads were selected to make a portable copper sulfate reference electrode, and the long-term stability and life of the electrode potential were tested. The results show that the size of raw material, sintering temperature and forming pressure have a significant influence on the pore size and porosity of porous ceramic head. With the decrease of the size of raw material, the increase of sintering temperature and forming pressure, the pore size and porosity decrease. The electrode potential of the portable reference electrode made of porous ceramic head with pore size of 522 nm and porosity of 17.4% has a long-term stability and the estimated life can reach 4.2 years.
