ABSTRACT:
A cylindrical ceramic foam body that can be the sole buoyant member of an oil-containment boom is produced by firing a mixture of fine particles of ceramic precursor, a source of carbon such as silicon carbide, and a metallic oxide. In the boom, a stack of the ceramic foam bodies, each of which is a cylinder, can be held together by wire mesh to provide a buoyant log. A plurality of the buoyant logs can be inserted end-to-end into a 3-layer loop, viz., an inner layer of a ceramic textile fabric, a middle layer of knitted wire mesh, and an outer layer of polymer-coated fabric.
