The invention relates to a method for producing a composite body and to a composite body produced using the method, wherein the composite body () is formed as a pressure pipe or as a pressure container, wherein the composite body is composed of a main body () that is made of steel and of a coat () that is made of a fiber composite (), said coat enclosing the outside of the main body at least in some sections, wherein, for forming the fiber composite, a fibrous material is wound around the main body, wherein the fibrous material is impregnated with a resin before or after winding, wherein the wound and impregnated fibrous material is heated in order to form the fiber composite, wherein the method is carried out in situ on a built-in pressure pipe or pressure container, wherein the wound and impregnated fibrous material is heated to up to 700&#xb0; C.

Method for producing a composite body

A method for the production of a ceramic substrate for a semiconductor component, includes the steps of producing paper containing at least cellulose fibers, as well as a filler to be carbonized and/or SiC, pyrolizing the produced paper, and siliconizing the pyrolyzed paper.

Method for the production of a ceramic substrate, and a ceramic substrate

Aqueous dispersion containing a metal oxide powder with a fine fraction and a coarse fraction, in which&#x2014;the metal oxide powder is silicon dioxide, aluminum oxide, titanium dioxide, zirconium dioxide, cerium oxide or a mixed oxide of two or more of the aforementioned metal oxides,&#x2014;the fine fraction is present in aggregated form and has a mean aggregate diameter in the dispersion of less than 200 nm,&#x2014;the coarse fraction consists of particles with a mean diameter of 1 to 20 &#x3bc;m, &#x2014;the ratio of fine fraction to coarse fraction is 2:98 to 30:70, and&#x2014;the content of metal oxide powder is 50 to 85 wt. %, referred to the total amount of the dispersion. The aqueous dispersion is produced by a process comprising the steps:&#x2014;production of a fine fraction dispersion by dispersing the pulverulent fine fraction in water by means of an energy input of at least 200 KJ/m3?, and&#x2014;introducing the coarse fraction in the form of a powder into the fine fraction dispersion under dispersing conditions at a low energy input. Process for the production of molded articles using the dispersion.

Highly-filled, aqueous metal oxide dispersion

A method for the production of a carbon or a ceramic component based on carbon, using a cellulose-containing semi-finished molded piece which is pyrolyzed. According to the invention, homogeneous large-size ceramic components may be produced, whereby a cellulose-containing, semi-finished molded piece containing fibers, chips or strands of homogeneous density distribution and homogeneous structure is used as semi-finished molded piece and is pyrolyzed in non-oxidizing gas atmospheres.
