  2. 1. Synthesis and Characterization of MgA1ON-BN refractories

    Author : Zuotai Zhang; Seshadri Seetharaman; Kazuhiro Nagata; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MgAlON-BN composites; Mechanical properties; Thermal shock durability; Thermal diffusivity conductivity; Corrosion resistance.; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : In order to meet the need of metallurgical industry in the world, a new MgAlON-BN composite which can be used for example in special refractory nozzles, tubes and break rings for the continuous casting of steel was studied in the present thesis. The aim was to understand the mechanism of synthesis and their physicochemical properties during the application. READ MORE

    Abstract : Growth, microstructure and mechanical properties of boron nitride: carbon (BN:C) have been studied in films prepared by reactive r.f. diode sputter deposition as well as by reactive unbalanced d.c. READ MORE

  5. 3. Studies on Growth of SiC and BN : from Theory and Experiments

    Author : Jenny Olander; Karin Larsson; Jan-Otto Carlsson; Alison Mainwood; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Growth; quantum chemistry; DFT; ALD; laser-activation; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : Smaller cellular telephones and more energy-efficient windows are just two examples of technological advances which call for new materials. Materials chemists seek to develop new materials, both out of pure curiosity to see which combination of elements and structures can be obtained and in efforts to produce materials, with specific properties.

  6. 4. Theoretical Routes for c-BN Thin Film Growth

    Author : Johan Karlsson; Karin Larsson; Sven Ulrich; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cubic boron nitride; chemical vapor deposition; density functional theory; adsorption; abstraction; Inorganic Chemistry; Oorganisk kemi;

    Abstract : c-BN has been in focus for several years due to its interesting properties. The possibility for large area CVD is a requirement for the realization of these different properties in various applications. Unfortunately, there are at present severe problems in the CVD growth of c-BN. READ MORE

  7. 5. Theoretical Routes for c-BN Thin Film Growth

    Author : Johan Karlsson; Karin Larsson; Sven Ulrich; Uppsala universitet; []
