Title:
AQUEOUS SOLUTION AND METHOD FOR SEPARATION OF CONDUCTIVE SINTERED CERAMIC MATERIAL
Document Type and Number:
WIPO Patent Application WO/2007/032503
Kind Code:
A1
Abstract:
Disclosed are an aqueous solution and a method which are used for separation of
a conductive sintered ceramic material, and which can separate a conductive
sintered ceramic material from a glass pane and collect the conductive sintered
ceramic material in a recyclable form. 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 sintered ceramic material and the conductive
sintered ceramic material wherein the conductive sintered ceramic material
formed on the dark sintered ceramic material. A treatment solution having an
etching effect against at least one of the glass pane and the conductive sintered
ceramic material is prepared as an aqueous solution (20) for separation of the
conductive sintered ceramic material. A vessel (11) is filled with the aqueous
solution (20), and the glass pane (30) having the conductive sintered ceramic
material attached thereon is immersed in the aqueous solution (20).
