particle size distribution curve for talc

Preparation of submicron talc particles by sonication
2005.1.1 The sonicated talc presents a bimodal particle size distribution with two modal sizes in the range of the submicrometers and micrometers, respectively. With the sonication treatment up to 40 h treatment, the volume percentage of the smaller particles increases as the volume percentage of the larger ones decreases.

Influence of talc morphology on the mechanical properties of talc ...
2013.4.30 Abstract. Injected polypropylene (PP)/talc composites were studied to evaluate the influence of different talc morphologies on their final mechanical properties. Talc genesis is responsible for type and content of associated minerals, crystalline degree, particle size distribution, and specially, morphology.
