Something that cannot form sediment or settle to the bottom of a liquid.
This word is used in scientific or technical contexts to describe substances or particles that do not settle in a liquid.
Examples:
The nonsedimentable particles remain suspended in the liquid.
This substance is nonsedimentable, so it stays mixed in the solution.
The nonsedimentable material floats in the liquid.
The nonsedimentable stuff is like magic - it never goes to the bottom!
The nonsedimentable particles are so light, they seem to defy gravity.
In the experiment, we observed the nonsedimentable material staying suspended in the liquid.
