  1. 1. Silicon Carbide Reinforced Alumina and Mullite Ceramics

    Author : Stefan Gustafsson; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ceramic Nanocomposites; Creep; SEM; SiC; Grain Boundaries; Microanalysis; Mullite; Pressureless Sintering; TEM; Alumina;

    Abstract : The aim of this work was to develop homogeneous ceramic nanocomposite materials with good thermal and structural stability as well as good mechanical properties. The development of microstructure was related to the material properties. READ MORE

  2. 2. Manufacture of long-fibre reinforced ceramics by reaction bonding

    Author : Jesper Brandt; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; weaves; slurry infiltration; fibre; aluminium oxide; reaction bonding; ceramic matrix composite; mullite; silicon nitride; alumina; CMC;

    Abstract : For several decades ceramic matrix composites has been of interest to be used as hot parts in certain high-performance gas turbine aero engines. In general, ceramic materials resist higher temperatures than superalloys. READ MORE

  3. 3. Properties of Ugandan minerals and fireclay refractories

    University dissertation from Stockholm, : KTH

    Author : John Baptist Kirabira; KTH.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; kaolin; clay; Ugandan minerals; fireclay; refractory; powders characterization; beneficiation; ceramics; mullite; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : Development of products which can be produced from a country’s natural resources is very important as far as the industrialization of a nation and saving foreign exchange is concerned. Presently, industries in Uganda and the other states in the Lake Victoria region import all refractory-related-consumables, as the demand cannot be met locally. READ MORE

  4. 4. Innovative process solutions towards recycling of salt cake from secondary aluminum smelting

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Peng Li; KTH.; [2012]

  5. 5. Degradation of mullite based materials by alkali containing slags

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Jesper Stjernberg; Luleå tekniska universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Engineering Materials;

    Abstract : Iron is one of the most important resources that can be found in the lithosphere; 90 % of all metal ores extracted are iron ore. Many steps are included in the extraction from iron ore to metallic iron, where the processes vary between different producers. Iron ore pellets, are a prepared burden material for ironmaking in the blast furnace. READ MORE
