  • Patent number: 5139191
    Abstract: The present invention relates to a method of connecting a ceramic material to another material. According to the present method as ceramic material porous material is used that prior to making a connection it is gradually compacted from the contact surface with the greatest density at the contact surface, wherein on the contact surface of the porous material a mixture of titanium hydride (TiH.sub.2) and quartz flour (SiO.sub.2) is applied. Then the so treated porous ceramic material is heated to 1200.degree.-1800.degree. C. during 1-40 hours. Finally the so compacted porous ceramic material in a manner known per se is connected to the other material. Preferably the treated porous ceramic material is heated to 1300.degree.-1500.degree. C. during 10-20 hours. Advantageously the weight proportion of TiH.sub.2 and SiO.sub.2 in the mixture is 95:5 to 5:95 and preferably 35:65 to 65:35.
