Powder Fineness (Types of Powder) : Pharmaceutical Guidelines

The degree of coarseness or fineness of a powder is expressed by reference to the nominal mesh aperture size of the sieves used for measuring the size of the powders. For practical reasons, the use of sieves for measuring powder fineness for most pharmaceutical purposes is convenient but devices other than sieves must be employed for the measurement of particles less than 100 ~ in nominal size.
