原料的充分混合是晶体生长过程的第一步。这适用于几乎任何标准技术，而离析物的有意分离被认为仅限于非常有限的情况。本文研究了在开放坩埚中，在空气中从分离的析出物中生长α-Li_2IrO_3单晶。元素锂和铱被氧化并在通常一厘米的距离上传输。与经典的蒸气输运相反，该过程基本上是等温的，温度梯度的重要性较小。单晶从置于离析物之间的暴露的冷凝点生长。该方法也被应用于Li_2RuO_3、Li_2PtO_3和β-Li_2IrO_3的生长。预期这种简单且低成本的技术可成功用于各种其他材料。
Thorough mixing of the starting materials is the first step of a crystal growth procedure. This holds true for almost any standard technique, whereas the intentional separation of educts is considered to be restricted to a very limited number of cases. Here we show that single crystals of α-Li2IrO3 can be grown from separated educts in an open crucible in air. Elemental lithium and iridium are oxidized and transported over a distance of typically one centimeter. In contrast to classical vapor transport, the process is essentially isothermal and a temperature gradient of minor importance. Single crystals grow from an exposed condensation point placed in between the educts. The method has also been applied to the growth of Li2RuO3, Li2PtO3 and β-Li2IrO3. A successful use of this simple and low cost technique for various other materials is anticipated.
