1. Zone refining is a process used to purify materials by passing a molten zone through a solid material.

区域精炼是一种通过将熔融区域穿过固体材料来纯化材料的过程。

2. The semiconductor industry often uses zone refining to produce high purity silicon crystals.

半导体行业经常使用区域精炼来生产高纯度硅晶体。

3. By carefully controlling the temperature gradient and moving the molten zone, impurities can be selectively removed from the material.

通过精确控制温度梯度并移动熔融区域，可以选择性地从材料中去除杂质。

4. Zone refining is a slow and precise process, but it is highly effective in removing impurities from materials.

区域精炼是一个缓慢而精确的过程，但它在去除材料中杂质方面非常有效。

5. The success of zone refining relies on the ability to create a sharp boundary between the molten and solid zones.

区域精炼的成功取决于能够在熔融区域和固体区域之间形成清晰的界限。

6. Researchers continue to study and improve the process of zone refining to make it more efficient and cost-effective.

研究人员继续研究和改进区域精炼的过程，使其更加高效和具有成本效益。
