  3. 2. Properties of Ugandan minerals and fireclay refractories

    Författare :John Baptist Kirabira; Stefan Jonsson; Thomas Johansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; kaolin; clay; Ugandan minerals; fireclay; refractory; powders characterization; beneficiation; ceramics; mullite; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : 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. LÄS MER

  4. 3. Silicon nitride-based materials for spinal and antipathogenic applications

    Författare :Ioannis Katsaros; Håkan Engqvist; Hanna Tiainen; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Silicon nitride (Si3N4) is a ceramic material that is well-established in industrial applications due to its stability in demanding environments. The mechanical properties and biocompatibility of the material have led to its approval for clinical use in spinal implants. LÄS MER

  5. 4. Synthesis of ytterbium-doped yttrium oxide nanoparticles and transparent ceramics

    Författare :Johanne Mouzon; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Materials; Materialteknik;

    Sammanfattning : In this thesis, the author reports on a ceramic process leading to transparent ytterbium doped yttrium oxide ceramics. The full production route was investigated, namely: powder preparation, compaction and sintering. First, yttria nano-powder was fabricated from a precursor with transient morphology, i.e. LÄS MER

  7. 5. Synthesis of Yb:Y2O3 nanoparticles and fabrication of transparent polycrystalline yttria ceramics

    Författare :Johanne Mouzon; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Engineering Materials;

    Sammanfattning : More efficient laser materials are needed for space applications in order to save weight and make cost-savings. The fabrication of polycrystalline ceramic materials is a solution to obtain new compositions with better efficiency. LÄS MER
