Abstract
A slurry containing microfiber and micropowders, and a process for making such a slurry, are provided. The slurry containing microfibers and micropowders is more stable and easier to process, and the micropowder is less likely to separate out of the slurry or agglomerate in comparison to a slurry containing only micropowder.

A microfiber and micropowder slurry comprising at least one liquid medium, at least one microfiber, and at least one micropowder.
A process for producing a slurry comprising at least one microfiber, at least one micropowder and a liquid medium, wherein said process comprises:
- premixing a starting material comprising at least one fiber with at least one liquid medium to form a premix;
- adding at least one micropowder to the premix;
- agitating the premix and the micropowder with a solid component for an effective amount of time to produce a slurry containing the microfiber and the micropowder;
- and removing the solid component.
A process for producing a slurry comprising at least one microfiber, at least one micropowder and at least one liquid medium, wherein said process comprises:
- mixing a microfiber slurry, at least one micropowder, for an effective amount of time to produce a slurry containing at least one microfiber and the at least one micropowder.
A process for producing a slurry comprising at least one microfiber, at least one micropowder and a first liquid medium, wherein said process comprises:
- premixing a microfiber slurry with at least one second liquid medium to form a premix;
