%X The role of ammonium salt of polyacrylic acid (NH4-PAA) in the dispersion of nanosized titanium nitride aqueous suspensions was investigated experimentally. Surface chemistry of the suspension was investigated by scanning auger microscopy (SAM). Zeta potential studies show that the isoelectric point of nanosized TiN powders is at pH=3.8 and NH4-PAA addition results in the shift of isoelectric point from pH=3.8 to pH =2. The adsorption of PAA-NH4 decreases as pH values increase, because PAA-NH4 is more negatively dissociated.
