  • Surface charge and particle dispersion of zirconia in aqueous suspension with addition of different dispersants, such as ammonium polymethacrylic acid (Darvan C), polyethylene imine (PEI) and diammonium citrate (DAC) were investigated by measuring its zeta potential and particle size. It was found that the zero point of charges (zpc) of 3Y-TZP powder was determined to be pHzpc=6, surface charge of zirconia powder changed significantly and zpc shifted under different dispersion conditions… CONTINUE READING
