A process for the manufacture of ceramic materials, in particular refractory elements, uses a binder, wherein the binder is used as an aqueous emulsion containing 1-4 pbw of water per 1 pbw of the binder. The materials thus obtained show an improved crushing strength while avoiding a harmful working environment. The binder may be a petroleum bitumen having a softening point of at least 80 DEG C, although it may also be e.g. polyethylene, polypropylene or polystyrene. Magnesite may be used as refractory material. |
