Abstract
The invention relates to porous, water-absorbent plastics mould material for use in the forming of ceramic castings from ceramic moulding materials. According to the invention they contain short fibres of length 1-6 mm in a quantity of up to 4 weight% with respect to the weight of the plastics content, as filler. The invention also relates to a process for producing these mould materials and their use in the forming of ceramic castings. Shrinkage and mechanical properties are considerably improved by the addition of short fibres, even in a very small added quantity. By producing the mould materials from water-in-oil emulsions the permeability of the mould materials can be adjusted within a wide range by controlling the degree of dispersion of the emulsion, so that both pressure-less and pressurized ceramic body formation and controlled release of the ceramic body from the mould by compressed air without the use of an aid become possible.
