Nanomaterial is a new material with many excellent properties, and has a prospective wide application. Nanomaterial is constituted by nanometer powder, so preparation of nanometer powder becomes important. Research and development of nanomaterial preparation are reviewed in the paper. With the preparation of alumina nanometer powder as an example, preparation techniques of nanometer powder, especially the preparation techniques of liquid synthetic, vapor synthetic and solid synthetic, are discussed. The advantages and disadvantages of various preparation techniques are also summarized in the paper.
