Understanding ADV and pH Testing for Mold, Core Sand ...

Q: Our foundry runs pH and Acid Demand Value (ADV) tests on our mold and core sands. Both of these tests measure the acidity or basicity of the sands. Why do we run both tests? A: Both pH and ADV are related to the acidity and basicity of the sand. When we consider the most common type of foundry sand, that is silica sand, both tests are related to the impurities normally found in the sand.

Zircon sand is rounded grain sand generally used in the same manner as chromite sand. Available AFS GFN may vary from 65-130, depending on the sand source. Produced from beach sand deposits, these form as a result of weathering processes followed by stream transport to seacoasts where heavy minerals are further concentrated by wave and wind action.
