Quick Summary

Densification is a process that reduces the volume of matter by drawing its particles closer together. This process is crucial in materials science, particularly in the creation of advanced ceramics, where powders are heated to bond together, reducing porosity and increasing density.12

Mass and density are distinct properties of matter. Mass measures inertia, while density describes how tightly matter is packed within a given volume. Density is calculated as the ratio of mass to volume: ( \text{density} = \frac{\text{mass}}{\text{volume}} ).3

Densification
Like traditional ceramics, advanced ceramics are densified from powders by applying heat—a process known as sintering. Unlike traditional ceramics, however, advanced powders are not bonded by the particle-dissolving action of glassy liquids that appear at high temperatures. Instead, solid-state sintering predominates. In…

…the intricate crystals and thus pack them more tightly. Thus, the density of the snowpack generally increases with time from an initial low value of 50–250 kilograms per cubic metre (3–15 pounds per cubic foot). The process of evaporation and condensation may continue: touching grains may develop necks of ice…
