INTRODUCTION • Micromeritics is the study of fundamental and derived properties of individual as well as a collection of particles and thus can be called the science and technology of small particles. • The particle size of a drug can affect its release from dosage forms that are administered orally, parenterally, rectally and topically.

Granular pharmaceutical solids, prepared by 5 different granulation methods, were evaluated on the basis of repose angle, hardness, density, number of particles per gram, bulk density, shape volume factor, bulk volume, and geometrical form. Particular attention was given to the development of an accurate technique for evaluating shape volume factor as a means of characterizing the over-all.

Nitrogen gas is commonly employed and the apparatus is quantasorb. A plot of p/V (p-p0) against p/p0 is a straight line with a slope and intercepts b and Vm. Air permeability method. The rate of penetration of a gas or liquid on to the powder is related to resistance to the flow of a liquid through a compact of powder.
