Of these, diatomaceous earth in particular has seen a revival as a non-toxic (when in amorphous form) residual pesticide for bed bug abatement.

Early research used an expensive additive called fumed silica, an amorphous form of silica made by combustion of silicon tetrachloride in a hydrogen-oxygen flame.

Heat causes such regions to become diffuse, so that the chains begin to separate into an amorphous form.

This irreversibly dissolves the starch granule, so the chains begin to separate into an amorphous form.

The tower's observation deck has an amorphous form, with several separate conical forms forming the glazed platforms.
