Method to improve the leaching process |
摘要 |
<p>A method to leach a component that includes a polycrystalline structure. The method includes obtaining the component having the polycrystalline structure. The polycrystalline structure includes catalyst material deposited therein. The method also includes performing a leaching process on the polycrystalline structure to an intermediate leaching depth. The leaching process removes at least a portion of the catalyst material from the polycrystalline structure and forms one or more by-product materials deposited therein. The method also includes performing a cleaning process on the polycrystalline structure, which removes at least a portion of the by-product materials. The leaching process and the cleaning process are iteratively continued until the intermediate leaching depth reaches a desired leaching depth, both of which are measured from one end of the polycrystalline structure. The desired leaching depth is greater than at least one intermediate leaching depth.
