粉体材料制造技术是现代材料科学中的主要组成部分之一,它的应用范围涉及到:医药、食品、催化剂、化妆品、军工、超导、半导体、生化等。 纳米级粉体材料的制造技术又是现代材料科学中的高新技术,是世界材料科学家当前所关注的热点。以同一种材料为例,纳米级材料的产品附加值比一般粉体材料高出几十至几百倍。 八十年代末期,为了控制药的释放效力(能),提高药品的效能和缓解、减弱药品对人体的副作用,各国医药科学家对药剂的微粒化展开研究,药品缓释
Powder material manufacturing technology is one of the main components of modern materials science. Its application scope covers: medicine, food, catalyst, cosmetics, military industry, superconductivity, semiconductor, biochemistry and so on. Nanometer powder material manufacturing technology is also a high-tech in modern materials science, which is currently the focus of attention of material scientists in the world. Taking the same material as an example, the added value of nanometer material products is several tens to several hundreds of times higher than that of common powder materials. In the late 1980s, in order to control the efficacy of drug release, improve the efficacy and mitigation of drugs, and reduce the side effects of drugs on human beings, medical scientists in various countries conducted research on the drug atomization,
