The ability of a substance to be distributed or spread throughout a medium, especially a liquid.
The dispersibility of the powder in water was tested to ensure it would mix evenly without clumping.
A quantitative measure (often expressed numerically) of how easily particles in a powder, suspension, or emulsion can be dispersed and remain uniformly distributed in a medium.
Engineers compared the dispersibilities of several formulations to select the one that would stay suspended the longest.
