Ph of tmah
WebbThe developer contains 2.38 to 2.62% tetramethylammonium hydroxide (TMAH) and ensures that the exposed areas can be readily separated from the substrate. The monitoring of the TMAH concentration in the developer solution takes place with a process analyzer from Metrohm Applikon that is configured specially for titration. Webb1 juli 2008 · At pH 9.0, the yield stress of ZrO 2 suspensions initially decreases with the increase of TMAH until 0.35 wt.%, reaches a minimum point and increases thereafter. It is apparent that the rheological properties are strongly dependent on the amount of the TMAH added, and 0.35 wt.% TMAH seems to provide the maximum coverage on the …
