摘要
Over the centuries, with the vigorous development of craftsmanship and the jewelry industry, the demand of jadeite, known as the "king of jade", has increased sharply in decoration and collection. However, the formation conditions of jadeite in nature are extremely harsh, which makes it difficult for its supply to meet people's needs. Therefore, the development of jadeite synthesis technology is of great benefit to the problem of insufficient supply of natural jadeite. It can not only promote the high yield of jadeite, but also can accelerate its marketization process. High temperature and high pressure method has been widely used to synthesize artificial jadeite. The key to this method is the synthesis of jadeite precursors and the conversion of vitreous amorphous jadeite to jadeite. In this process, to prepare the jadeite precursor under a relatively mild condition is thus a key point, but several challenges still remained. This review discusses the latest research hotspots and applications of jadeite synthesis at home and abroad in recent years, focusing on three conventional preparation techniques for jadeite precursors: solid-phase sintering method, chemical synthesis method and sol-gel method. At the same time, the advantages and disadvantages of various methods are evaluated, and the future development of artificial synthetic jadeite is also prospected.
