Abstract

An insulating feed unit for use in casting, comprises hollow ceramic spheres with a density of less than 0.3 g/cm3, a hardened binding agent, and fibre material. The unit is produced by mixing the spheres, the binding agent and the fibre material, then forming the mixture and hardening it.
