Abstract

This application relates to insulating, ceramic, porous articles, especially for fire insulating products, acoustic insulating products and thermal insulating products. More specifically, the invention relates to a method of production of the insulating, ceramic, porous article. According to the production method of this invention, an elastic porous form is filled with a liquid ceramic mixture. The elastic form is initially squeezed, then immersed in the liquid. When the pressure is released it needs to be able to absorb the liquid ceramic mixture into its pores and hold it there after the pores are filled and the form is removed from the liquid. During subsequent drying and firing, the porous structure in created in original way - via release of liquid which made a large percentage of the liquid mixture. The elasticity of the form used is an important, positive factor in enabling large volume changes without damaging the ceramic porous article. If the liquid mixture contains refractory material, the resulting product can be used as lightweight insulating firebrick.
