With Al 2( SiO 3)3 and Na 2 SiO 3 ⋅ 9 H 2 O as raw materials, the NaAlSi 2 O 6 jadeite was synthesized in the temperature range of 1000–1600°C under 5.0 GPa conditions. Amorphous glass materials are entirely converted to crystalline NaAlSi 2 O 6 jadeite at 5.0 GPa and 1450°C. All the experimental results reveal that the properties of synthetic NaAlSi 2 O 6 resemble the natural jadeite very much. The research indicates that we provide a new approach to synthesize NaAlSi 2 O 6 and offer an essential guideline for jewelry, which will be helpful for deep understanding on the origin of natural jadeite and the metamorphism of magma within the Earth.

Microstructure And Properties

The method of high pressure and high temperature (HPHT) has been used for the synthesis of jadeite. Through this method, the NaAlSi2O6 jadeite can be obtained in the pressure range of 4.0–5.5 GPa. All the experimental results reveal that the microstructure and properties of synthetic jadeite resemble the natural jadeite very much. The research indicates that the crystallization temperature of the synthesized NaAlSi2O6 jadeite rises with the increase of the pressure, which will help in gaining a deep understanding on the origin of natural jadeite.

AbstractThe non-centrosymmetric scandium borate ScB6O9(OH)3 was obtained through a high-pressure/high-temperature experiment at 6 GPa and 1473 K. Single-crystal X-ray diffraction revealed that the structure is isotypic to InB6O9(OH)3 containing borate triple layers separated by scandium layers. The compound crystallizes in the space group Fdd2 with the lattice parameters a = 38.935(4), b = 4.4136(4), and c = 7.6342(6) Å. Powder X-ray diffraction and vibrational spectroscopy were used to further characterize the compound and verify the proposed structure solution.
