摘　　要：采用混合研磨技术,以1250目的滑石粉为原料,六偏磷酸钠为助磨剂,制备了平均粒径为85.6nm的纳米滑石粉。通过粒度分布、TEM、矿浆粘度、电位和IR分析,研究了混合研磨法制备纳米滑石粉的机理,考察了六偏磷酸钠对滑石粉的助磨机理。Hybrid milling method was utilized and nano-talcum powder with median size of 85.6nm was pre pared by adding sodium hexametaphosphate. The products were characterized by particle size distribution, TEM, slurry viscosity, potential and IR. The mechanism of hybrid milling and grinding mechanism of sodium hexa-meta phosphate in the grinding process were investigated.
