Heat exchangers and flow reactors made from silicon carbide pave the way for the modern synthesis of valuable fine chemicals and pharmaceuticals under controlled and safe conditions. The production of such apparatus includes our developed process for joining SiC into complex monolithic shapes. By integrating the ceramic into a system it makes for resource- and energy-efficient processes in the target industries. An overview is given of the processing steps involved in the production of silicon-carbide heat exchangers and flow reactors, including powder synthesis, powder processing, forming, sintering and assembly. For each of these processing steps, the current state of development and challenges are addressed from our perspective. Source

The invention relates to boron nitride agglomerates, comprising lamellar, hexagonal boron nitride primary particles, which are agglomerated with one another with a preferred orientation, the agglomerates formed being flake-shaped. The invention also relates to a method for producing said boron nitride agglomerates, characterized in that lamellar, hexagonal boron nitride primary particles are agglomerated in such a way that they line up with one another with a preferred orientation. The flake-shaped agglomerates according to the invention are suitable as filler for polymers for making polymer-boron nitride composites and for hot pressing of boron nitride sintered compacts.

The invention relates to a suspension for producing a friction-increasing layer on a substrate, which comprises a liquid suspension medium, a predominantly inorganic binder or precursor compounds thereof and suspended hard material particles. The invention further relates to a shaped body comprising a substrate and a friction-increasing layer which has been applied to at least part of the surface of the substrate and comprises a predominantly inorganic binder matrix and hard material particles embedded therein, where the thickness of the binder matrix is less than the average particle size of the hard material particles so that the hard material particles project from the binder matrix and where the friction-increasing layer has been formed from a suspension according to the invention. The invention likewise relates to a process for producing the abovementioned shaped bodies and also their use for producing press or clamp connections and also as securing element.
