raising thermal conductivity with hexagonal boron nitride
Armin Kayser of ESK ceramics introduces a new generation of hexagonal boron nitride fillers for producing thermally-conductive compounds that are also electrically-insulating
Thermoplastic compounders are facing new challenges and opportunities in high-volume end-user markets, such as LED systems plus vehicle electric drive systems and batteries. However, for many applications in these markets, metal replacement will only be possible if injection moulded parts can offer sufficient thermal conductivity.

Sand Control with Ceramic Screens in Unconsolidated Reservoirs demonstrated in the mature Gaiselberg Oilfield
The Oil Production in the operation Centre ZIstersdorf of the Rohöl-Aufsuchungs AG (RAG) looks back to a long history and to a great variety of different types of completions. After the first oil bearing well RAG-002 in 1937 the development of the RAG field started, followed by more explorations successes in the Gaiselberg oil field 1938 onwards.

Drilling for Oil and Gas, Ceramics Make the Difference
A PetroCeram® thrust bearing employing advanced ceramics has been developed using hydrodynamic technology which minimizes wear and significantly decreases bearing frictional losses. With the thrust bearing acting as one of the primary sources of power loss in the motor, this reduction in frictional losses greatly increases available power to the bit meanwhile reducing the burden on the rig required to achieve similar drilling Rates of Penetration (ROP). In addition, downhole bearing longevity and reliability is increased resulting in a significant reduction in costly premature motor pulls.

Boroneige® boron nitride powder for skin care applications
Hexagonal boron nitride is a synthetic ceramic material at the forefront of technology. In cosmetics, boron nitride has long been used as a filler in make-up products, such as eye shadows, blushes, foundations, concealers and face powders, where softness, lubrication, spreadability, skin adhesion and opacity are desired. In a series of experimental trials, it showed optimal sensory characteristics. Moreover, it reduces the luster of greasy skin. Even small amounts (around 1%) in o/w emulsions accelerate the perceived skin absorption of cosmetics, while reducing the greasiness and tackiness of the residual film. In w/o emulsions, boron nitride has been reported to exert a stabilizing effect, while increasing product spreadability and skin smoothness.

Hydrodynamic Thrust Bearings for Downhole Mud Motor Use
A thrust bearing employing advanced ceramics has been developed using hydrodynamic technology which minimizes wear and significantly decreases bearing frictional losses. Consequently, downhole bearing longevity and reliability is increased resulting in a significant reduction in costly premature motor pulls.

The Development of Ceramic Screens to Prevent Sand Influx and Erosion in Stimulated Production Wells
The Danish oil and gas fields, operated by Maersk Oil on behalf of the DUC (Danish Underground Consortium), a collaboration between A.P. Møller – Mærsk A/S, Shell Olie- og Gasudvinding Danmark B. V. (Holland) and Chevron Denmark Inc., are mainly tight Cretaceous carbonates with permeabilities in the range of 0.5–2.5 mD. All the wells need to be stimulated before they can be brought into production at economic rates.
