Micromeritics
Sign in to saveMicromeritics is the science of the behavior of particulate materials smaller than 75 μm. It is thus the study of the fundamental and derived properties of individual as well as a collection of particles. Micromeritics involves materials with larger particles than nanoparticles where they are smaller than 0.1 μm.

Micromeritics is the science of the behavior of particulate materials smaller than 75 μm. It is thus the study of the fundamental and derived properties of individual as well as a collection of particles. Micromeritics involves materials with larger particles than nanoparticles where they are smaller than 0.1 μm.
The knowledge and control of the size of particles has importance in pharmacy and materials science. The size, and hence the surface area of a particle, can be related to the physical, chemical and pharmacological properties of drugs. Clinically, the particle size of a drug can affect its release from dosage forms that are administered orally, parenterally, rectally and topically. The successful formulation of suspensions, emulsions and tablets; both physical stability and pharmacological response also depends on the particle size achieved in the product.
