Silica or alumina are both available in a variety of sizes. The size is given by the mesh value which refers to the number of holes in the mesh that is used to sieve the absorbent. Thus higher mesh values such as "silica gel 230–400" have more holes per unit area and correspondingly smaller particles than "silica gel 60".

Silica sand is a combination of silica atoms (up to 96%) with oxygen atoms, presented in small grains or what we know as sand. This is combined with gravel, which comes from the breakage or fragmentation of other rocks and thus forms silica sand for use with artificial turf. Its primary function is to ballast or place weight, but it has many more.
