Whisker is a single form of growth under the artificial control which has large length diameter ratio of single crystal fiber material, the diameter is small, the strength is close to the theoretical value, as modified materials exhibit excellent physical and mechanical properties. With the rapid development of modern science and technology, new composite materials with high strength, high modulus, high temperature resistance has become the needs of industrial development, the whisker has excellent physical mechanical properties, make it in the strengthened material exhibits excellent application prospects. This paper first introduces the basic connotation, the characteristics of nano materials and the development of history, and the methods of characterization and other related content; the current magnesium borate nano materials is introduced in detail, and then fully elaborated on his research work carried out. By means of XRD analysis were used to characterize the effect of different additives, system parameters on the final product, determined the optimum process conditions. The final results show that the Na2CO3 and Mg (NO3) 2 · 6H2O as reactant, respectively by NaH2PO4, Na2HPO4, 12H2O, polyvinyl alcohol as additive, the additive amount were 0%, 0.5%, 1%, 1.5%, 2%, can obtain magnesium carbonate whisker product better.
