The element 3,8 13,16 provides a higher radiating surface area to volume ratio than a conventional tubular element. Cold tails 4,5 are provided separately 4,5 or integrally 9,10 with the element which may be extruded and bent to shape, eg U shaped, prior to drying and firing. The heating section may be recrystallised to form self bonded silicon carbide material or the final product may comprise reaction bonded or reaction sintered silicon carbide. |
