The authors have recently researched interesting phenomena on lapping tests for a glass on a silver lapping plate using different quaternary ammonium chloride solutions. The silver lapping plates were not worn during the lapping process even under the condition of large stock removal of the glasses. In this research, glasses, silicon wafers and ceramics were used as lapping plates for lapping test in the various quaternary ammonium chloride compound solutions as suspensions with aluminium oxide abrasive grains. It inquired into relations between the phenomena and concentration of NaCl, KCl, NH_4Cl and ZnCl_2 solutions, too. The surfaces of silvers were observed by SEM and EDX after lapping test. In the case when NaCl, KCl, NH_4Cl and ZnCl_2 lapping solutions were used on glass lap plate, also stock removals of silvers become zero. Any differences of structures on the silver surfaces were not observed after lapping by SEM and EDX even if this phenomenon occurred or not.
