    Description:
    DESCRIBE THE PROCESS BEHIND THE SURFACE FUNCTIONALISATION / TREATMENT:

    - Main features of the surface treatment/functionalisation process: Prevention of agglomeration of powders.

    - the type of process/reaction (hydrolysis, oxygen treatment, acid washing, etc.): Wet mixing with calcium carbonate, pH-adjusted crystallisation, calcination.

    - relevant ranges of process parameters such as reaction conditions (pH, temperature): pH 12-13, temperature 90-180°C.

    - any purification step: None

    - Molar ratio of each surface treating agent used: Mass Ratio of 0.3% - polydimethylsiloxane is a polymer and will have a distribution of molecular weights. This makes it impractical to calculate the number of mols added and hence the molar ratio.

    - Functionalities introduced by the treatment (e.g. carboxyl, amino, hydroxyl groups): Not applicable
