Syllabus Basics of micromeritics- Fundamental and derived properties of powders and their measurement-particle shape & size, surface area, densities, flow properties, packing properties, fluidization of powders. The word Micromeritics refers to a discipline of science and technology that deals with studies related to the fundamental as well derived properties of particles. A precise knowledge of the particles size is of supreme importance in the pharmaceutical and materials science. Micromeritics is the science and technology of small particles . The unit of particle size most frequently used in micromeritics is micrometer, also called as a micron. Applications 1) Release & Dissolution Particle size & surface area influence the release of a drug from a dosage form that is administered orally, rectally parenterally & topically. Definition: It is the science and technology of small particles deals with fundamental and derived properties of individual and collection of particles In the field of pharmacy, micromertics has become an important area of study because it influences a large number of parameters Research and development manufacturing of dosage forms such as

Banker, James Swarbrick, School of Pharmacy and Pharmacal Sciences, Purdue University, Lafayette, Ind. School of Pharmacy and Pharmacal Sciences, Purdue University Lafayette Ind Granular pharmaceutical solids, prepared. 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.

importance in pharmacy. thus, size, and hence surface area, of a particle can be related in a significant way to the physical, chemical, and pharmacologic properties of a drug. IMPORTANCE OF THE MICROMERITICS: 2 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.

Introduction of Micromeretics L1 Unit4 Physical PharmaceuticsII
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.
