pH Control in Investment Casting Slurries REMET

A good range for slurry pH is 9.6-9.8. Some foundries prefer to keep slurry pH in a higher range, 9.5-10.0. If slurry pH has been allowed to drop to the 9.0-9.2 level, care must be taken not to shock the slurry. Adjustments to bring slurry pH into a higher range should be done in two or more steps rather than in one large step.
