Heteroagglomeration as a mechanism of retaining CaCO3 particles on the fibrils of cellulosic fines: A study by laser light diffraction and microscopy

- Laser-light size distributions tested for binary suspensions of colloidal particles.
- Attachment of CaCO3 to nano-scale cellulosic fibrils demonstrated.
- Mutual agglomeration found with negative zeta potential for both particle types.
- Laser diffraction results were verified by light microscopy.
