ABSTRACT:
Hydrothermally cured articles are formed by mixing a filler and a binder, moulding this mixture and coating said moulded articles with silica or calcium hydroxide particles. Hydrothermal curing may comprise a first step, wherein the steam pressure in the autoclave is increased, thereafter the steam pressure is decreased and subsequently the pressure is increased to a steam pressure being higher than in the first step.
