Laboratory Test Request

Manganese Dioxide Powdered Mixture Drying Rate and Water Activity Testing

Project Description

Large Corporation needs a laboratory conducting a study of powdered mixture of ingredients, consisting primarily of Manganese Dioxide, in the production of alkaline batteries and need to understand how the moisture in the environment affects the drying or absorption of water in our product.

This material is finely powdered and blended in the lab, then compacted/granulated to a larger particle size and finally tableted (similar to a pharmaceutical tableting operation).

The testing to be performed should at least include measuring the Water Activity of our product and the drying rates to reach the equilibrium moisture content. The isotherms need to be found at the conditions we experience in manufacturing as well as for various compositions of this material. Any recommendations on other tests that can be performed are welcome.
