我们用溶液在热梯度场中生长的方法合成了无水、含水、含铁的大尺寸(0.7-1.0 mm)的铁闪锌矿晶体。以K2 Mg(CO3)2为溶剂，在16.5 GPa1700℃下生长了含84±17wtppm H2O的(-lt；68±4wtppm H2O)Mg2SiO4晶体。以2KHCO3-Mg(OH)2为溶剂，在1400℃、15.5 Gpa的压力下合成了1496±117wtppm H2O的无铁水滑石晶体。
Abstract We have synthesized large (0.7-1.0 mm) crystals of anhydrous, water-bearing, and Fe-bearing wadsleyite by means of growth from solution in the thermal gradient field. Nearly anhydrous (<68±4 wt ppm H2O) Mg2SiO4 crystals were grown using K2Mg(CO3)2 as a solvent at 16.5 GPa and 1700 °C. (Mg0.92Fe0.08)2SiO4 crystals containing 84±17 wt ppm H2O were grown using 92K2Mg(CO3)2-8FeCl2 as a solvent. Crystals of Fe-free wadsleyite with 1496±117 wt ppm H2O were synthesized at 1400 °C and 15.5 GPa by using 2KHCO3-Mg(OH)2 as a solvent.
