摘要: 本文通过1 350~1 550 ℃高温灼烧得到了具有翡翠成份的玻璃,在压力2.0~4.5 GPa、温度900~1 450 ℃下完成了翡翠由非晶态到晶态的转变,合成出83 mm的翡翠。通过适量的Cr、Cu、Co等离子掺杂染色,得到了翠绿色、朱红色和蓝色的翡翠。本文还研究了压力和温度对翡翠合成的影响。Abstract: The synthesis of jewelry jadeite at pressures of 2.0~4.5 GPa and temperatures of 900~1 450 ℃ is described in this paper. The size of the synthetic jadeite is about 83 mm. The jadeite was synthesized from jadeite glass made at 1 350~1 550 ℃. By adding certain amounts of Cr3+, Cu2+, Co3+ cations, jadeite with emerald green, red and blue colours has been obtained respectively. The effects of pressure and temperature on the synthesis of jadeite are also discussed.
