Using a mixture of konjak flour and welan gum as a binder for the ceramic and powder-metallurgical molding

The invention relates to the use of a mixture of konjak flour and welan gum as a binder for the ceramic and powder-metallurgical molding. The inorganic grit used in the molding may be made of oxide, non-oxide ceramics, carbon or metallic grains. The particle sizes of the raw materials used, the inorganic particle size range from 50 nm to 10 mm. The binder used in the invention is particularly suitable for conventional slip-casting, for Druckschlickerguss, for the casting of vibrating masses and self-flowing materials, as a binder in malleable masses during extrusion, as binders for the production of thin-walled products by means of the tape casting and paper technology, and also as binders in the granulate preparation for the compression molding. The object of the invention is to develop an environmentally friendly binder for the ceramic and powder-metallurgical molding, which leads to a higher green strength of the briquettes and during the demolding to high-quality surfaces. According to the invention, the object is achieved in that a mixture of konjak flour and welan gum is used as a binder for the ceramic and powder-metallurgical molding.
