强化玻璃及使用差分化学制造其之方法;STRENGTHENED GLASS AND METHODS FOR MAKING THE SAME BY USING DIFFERENTIAL CHEMISTRY

摘要

本发明提供一种利用交换介质及经改质交换介质强化基板之方法，该基板包括富处理区域及贫处理区域，该方法包含：将该经改质交换介质施用至该富处理区域之表面；及将该交换介质施用至该贫处理区域之表面，其中该交换介质包括包含入侵硷离子之组成且该组成与该入侵硷离子之离子交换速率相关；该经改质交换介质包括包含入侵硷离子之经改质组成且该经改质组成与该入侵硷离子之经改质离子交换速率相关，且其中该经改质离子交换速率比该离子交换速率慢。; the method containing: applying the modified exchange medium to a surface of the treatment-rich volume; and applying the exchange medium to a surface of the treatment-poor volume; in which the exchange medium including a composition including an invading alkali ion and the composition is associated with an ion exchange rate of the invading alkali ion; the modified exchange medium including a modified composition including invading alkali ion and the modified composition is associated with a modified ion exchange rate of the invading alkali ion, and in which the modified ion exchange rate is slower than the ion exchange rate.
