INORGANIC FOAM PRODUCING METHOD AND A FOAM PRODUCED ACCORDING SAID METHOD

摘要

The invention relates to an inorganic foam producing method consisting i) in producing a substantially homogeneous suspension containing water, an inorganic powder and a stabiliser, ii) in adding a substantially non-water-miscible and substantially non-polar liquid and an emulsifier into said suspension, iii) in homogenising and emulsifying said mixture in such a way that an emulsion is obtainable, iv) in foaming the emulsion obtained at the stage iii) by evaporating the substantially non-polar liquid during drying in such a way that an inorganic foam body is obtainable and v) in sintering said inorganic foam body. The use of polymer substitutes, complex foaming methods and a stabilisation/fixation of the foam structure by binding agents is superfluous during the production of the inorganic foams.
