| 内容： | Disclosed are an aqueous solution and a method which are used for separation of a dark sintered ceramic material, and which can separate a glass pane from a glass pane having a dark sintered ceramic material attached thereon readily in a recyclable state. Also disclosed are an aqueous separation solution and a separation method which can separate and collect a dark sintered ceramic material, a conductive sintered ceramic material and a glass pane separately from a glass pane having the dark-colored sintered ceramic material and the conductive sintered ceramic material formed thereon. A treatment solution (e.g., hydrogen fluoride, a mixture of ammonium fluoride and an acid) having an etching effect against at least one of a glass pane and a dark sintered ceramic material is used as the aqueous solution (20) for separation of a dark sintered ceramic material. A glass pane (30) having a dark sintered ceramic material attached thereon is immersed in the treatment solution. An A-type treatment solution is added to a vessel (11) and the glass (30) is placed in the vessel (11). |
