Abstract
A thermal radiation baffle for apparatus for use in directional solidification of crystalline material, to be mounted at one end of a furnace, and to allow a mould containing the material in molten form to pass through, has at least one clamped layer of interconnected flexible strips of refractory material. Each such layer has an ordered construction, for example, with the strips being interwoven, or knitted; and has one or more slits therein. At least substantially the whole of each slit is inclined at a significant angle to the strips, so that the strips do not become detached or worn in use, but the layer is capable of resiliently engaging the sides of, for example, an irregularly shaped mould. A slit may be provided between two separate, but adjacent, pieces of the layer.
