Patent ID: 7799250

Claim:
A process for producing a ceramic brake lining comprising a material consisting essentially of magnesium oxide which is present in the form of ceramic particles bound by carbon and/or carbides, wherein the material has a mass fraction of at least 50% of magnesium oxide, wherein the cohesion of the material is effected by bonding with carbides, wherein a shapeable mixture of pulverulent magnesium oxide, carbide-forming metals selected from the group consisting of Ti, Ni, and Cr, additives comprising carbon fibres be present in a volume fraction up to 35%, and thermally curing organic binders is produced in a first step, this mixture is brought into the desired shape by pressing in a second step to provide a shaped mixture, and the shaped mixture is cured to produce a green body with the aid of the said thermally curing organic binders in a third step, and the green body produced in this way is carbonised in a fourth step at temperatures above 650° C. and in the absence of atmospheric oxygen, wherein carbon is formed during carbonisation, and carbides are formed in a thermal treatment carried out at a temperature of at least 1200° C. from the added carbide-forming metals selected from the group consisting of Ti, Ni, and Cr, and the carbon formed during the said carbonisation by decomposition of the said organic binders, which carbides form an inorganic binder phase during the said thermal treatment and bind the said magnesium oxide.
