摘要：
Al2O3-coated graphite powder was prepared using ethyl acetoacetate aluminum diisopropoxide through the sol-gel method. The fluidity of the Al2O3-coated graphite powder slurry was studied. The apparent viscosity of a 2 mass% Al2O3-coated graphite powder slurry was lower than that of a graphite powder slurry in the range of 25-40 mass% solid loading. It is concluded that the fluidity of the Al2O3-coated graphite powder slurry depends on the fraction of free water of the slurry, the degree of dispersion and the wettability by water of the Al2O3-coated graphite powder.
