求翻译：The authors studied the hydrothermal synthesis of alpha-Al2O3 from cheap alumina tri-hydrate. It was found that high purity alpha-alumina could be prepared at a relatively low temperature. Moreover, transition aluminas were absent in the final product, and a purity up to 150 ppm level was readily attained. As the cost 是什么意思？ 待解决

作者从廉价的氧化铝三水合物研究的水热合成α- Al2O3的。结果发现，高纯度α-氧化铝可以在一个相对较低的的温度下准备。此外，过渡氧化铝在最终产品中缺席，而且很容易达到一个纯度高达150 ppm水平。由于氢氧化铝成本相比要少得多，以纯金属铝，描述的过程具有良好的商业化潜力。
