Determination of Maximum Packing Fraction Pf by Oil Absorption Procedures

2 Determination of Maximum Packing Fraction (Pf) by Oil Absorption Procedures 

Oil-absorption results are usually quoted as cubic centimetres of oil per 100 grams of particulate at the end point. Simple mathematical treatment using oil and particle densities can then convert this to a volume fraction. As a guide, linseed oil absorptions for calcium carbonate of 20 cm 100 g and 50 cm 100 g correspond to filler volume fractions of 0.64 and 0.41, respectively.
