  • Well-crystallized jadeite was successfully synthesized from its glass phase under high pressure and high temperature conditions by simulating the mineralization principle of natural jadeite.Some of the synthetic jadeite samples present highly saturated colors and smooth finish which are the main features of high quality jadeite.The results of X-ray diffraction (XRD) and scanning electron microscopy (SEM) characterization show that the jadeite samples possess a relatively high degree of crystallinity and exhibit a good texture structure with vitreous luster and an appearance exactly like those of natural jadeite.The jade samples were also studied in detail by confocal micro-Raman spectroscopy.It is observed that the sharp Raman bands of synthetic jadeite samples are consistent with those of the natural jadeite.The differential scanning calorimetry (DSC) curve indicates that the thermal stability of synthetic jadeites is the same as natural jadeite.The hardness and density of synthetic jadeite measured are also similar to natural jadeite.In addition, it is found that the temperature plays a quite important role in crystal growth and knitting structure in terms of the synthetic jadeite samples.
