    Abstract: The invention relates to the area of and concerns a method for producing oxygen-containing hard materials, which can be used for instance in bearings. The invention has the task of providing a simple method for producing oxygen-containing hard materials with stoichiometric and substoichiometric compositions. According to the invention, this is done by grinding with carbon and homogenizing an oxide of the metals of the IV and V subgroup of the PTE, or mixtures of oxides of the metals of the IV, V and VI subgroup, or one or more metals of the IV and/or V subgroup or of the IV and V and VI or of the IV and VI or of the V and VI subgroup and one or more oxides of the metals of the IV, V and VI subgroup, the powder mixture being heated continuously or discontinuously at a temperature of up to 2,500 DEG C.

    Abstract: Ceramic compositions which are of particular value in the handling or casting of steel, for example as lining materials or for producing nozzles or shrouds used in continuous casting, comprise a mixture of particles of boron nitride, zirconium diboride and at least one other refractory material, bonded together by carbon produced by the decomposition of an organic binder such as a resin or pitch. The other refractory material may be for example a refractory metal, an oxide, a carbide, a boride or a nitride. Zirconium oxide containing compositions comprising 5-70 % by weight boron nitride, 5-60 % by weight zirconium diboride and 5-80 % by weight of zirconium oxide are particularly suitable for forming at least that part of a nozzle which in use is at the slag line in a molten steel vessel. Aluminium oxide containing compositions comprising 5-70 % by weight boron nitride, 15-50 % by weight zirconium diboride and 10-70 % by weight aluminium oxide are particularly suitable for forming the inside of nozzles as they resist alumina build up and prevent clogging of the nozzles.

    Abstract: A refractory comprising 60 to 95 wt % of magnesia or both magnesia and spinel, 3 to 20 wt % of carbon, and 2 to 15 wt % of silicon carbide in which 2 to 50 mu fine particles account for 85 % or more. This refractory prevents a decrease in the amount of contained carbon and minimizes abrasion when heated to high temperatures, because silicon carbide decomposes, when heated, to precipitate carbon which makes up for the loss of carbon in the refractory. This refractory is used for inner lining of vessels for previous treatment of molten pig iron.
