Novel refractory exothermic heat insulating articles for use in the metallurgical industry have a density < 0.75 g/cc. They are formed by removing liquid from a slurry. The slurry solids content includes a binder, 8-20 wt. % particulate oxidisable material, 5-25 wt. % fibrous refractory material, 5-20 wt. % expanded perlite and an oxidising agent for the oxidisable material. The perlite in its dry powder state has an untampered bulk density < 0.15 g/cc.
