  1. 1. Uranium nitride synthesis by gas/gas reaction of UF6 and NH3

    Master-uppsats, KTH/Fysik

    Författare :Serena Ambrosino; [2024]
    Nyckelord :Uranium nitride; synthesis; ammonolysis; uranium hexafluoride; uranium tetrafluoride; ammonia; X-ray diffraction; microscopy; Urannitrid; syntes; ammonolys; uranhexafluorid; urantetrafluorid; ammoniak; röntgendiffraktion; mikroskopi;

    Sammanfattning : This thesis project aims to develop an innovative technique for the production of high-purity uranium nitride (UN) through the ammonolysis of fluorides. The desired objective is to perform a controlled gas/gas reaction between uranium hexafluoride (UF6) and ammonia (NH3) at 800°C. LÄS MER

  3. 2. Theoretical examination of temperature distribution in an electrical furnace by the study of transient heat conduction effects

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Materialteori

    Författare :Judith Bösenecker; [2023]
    Nyckelord :sintering; heat transfer; transient heat conduction; sintring; värmeöverföring; transient värmeledning;

    Sammanfattning : The company Kanthal produces electric heating elements that require high temperature treatment in one production step. In this process step, called sintering, the amount of heat received by the sintered material is in direct correlation to the product’s outcome. LÄS MER

  4. 3. The Effect on Mechanical Properties in Biochar Replaced Cement & Aggregate in Concrete Before and After Fire Exposure

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Felix Hansen; Mathias Berglund; [2023]
    Nyckelord :Biochar; Concrete; Sintering; Fire; Mechanical properties; Sustainability; Cement; Biochar in concrete; Building industry; Concrete exposed to fire.; Biokol; Betong; Sintring; Eld; Mekaniska egenskaper; Hållbarhet; Cement; Biokol i betong; Byggindustri; Brandexponerad betong.;

    Sammanfattning : Concrete is good as a construction material regarding fire and its properties regarding strength. However, the concrete expands and cracks due to fire resulting in structural damage. According to the literature the concrete usually loses its strength during and after fire exposure due to themechanical and physical changes. LÄS MER

  5. 4. Mathematical modelling of Degussa Furnace

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Rans Faraydoun Muhammed; [2021]
    Nyckelord :Furnace; CFD; ANSYS; Thermodynamic model; Exchange time; Ugn; CFD; ANSYS; Termodynamisk model; Utbytestid;

    Sammanfattning : The energy demands in the world is rapidly increasing and with this,  a supply nuclear  power  is  of  much  interest.    Nuclear  fuel  is  relatively  efficient  when comparing to power sources like wind­ and hydropower plants. LÄS MER

  7. 5. Evaluation of new powder grade for furnace control pieces in sintering process

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Selma Halilovic; [2021]
    Nyckelord :;

    Sammanfattning : To be able to supervise the quality of a sintering process, furnace control pieces are therefore used. The current furnace control piece is not sensitive enough small variations during insert production. LÄS MER
