Object of the present investigation is b-sialon powder obtained by plasma-chemical synthesis. The powder is a solid solution of Al2O3 in b-Si3N4 and its particles with close to spherical shape are about 50 nm in diameter and their specific surface is 50 m2/g. To produce a resistant to aggressive and sedimentation lubricant, ultradispersed sialon underwent treatment with surfactants showing different ion activity and, correspondingly, different dispersion ability. Cation-active surfactants bring about wedging pressure as a result of double electric layer formed on the particles, thus hampering agglomeration of ultradispersed particles. Nonionogenic surfactants effect weakly particle dispersion, however jointly with cation-active surfactants assist sedimentation and improve colloidal system stability.
