  • Deposition of SiC/Si coatings in a microwave plasma-assisted spouted bed reactor 
    Van Laar, Jean H.; Bissett, H.; Barry, J.C.; Van der Walt, I.J.; Crouse, Philippus L. (Elsevier, 2018-04)
    Silicon carbide (SiC) layers were deposited onto alumina particles in a microwave plasma-assisted spouted bed reactor using methyltrichlorosilane (MTS) and hydrogen mixtures, in argon, as precursor gas feed. The operating ...
  • Deposition of silicon carbide coatings on alumina particles in a microwave plasma-assisted spouted bed reactor 
    Van Laar, Jean H. (University of Pretoria, 2018)
    Alumina particles were successfully coated with silicon carbide (SiC) layers in a microwave plasma-assisted spouted bed reactor. Methyltrichlorosilane (MTS) was used as precursor for the SiC deposition reaction, and argon ...
  • Microwave-plasma synthesis of nano-sized silicon carbide at atmospheric pressure 
    Van Laar, Jean H.; Slabber, Johan F.M.; Meyer, Josua P.; Van der Walt, Izak J.; Puts, Gerard Jacob; Crouse, Philippus L. (Elsevier, 2015-04)
    A microwave plasma process operating at atmospheric pressure was developed for the synthesis of SiC nanoparticles. The process utilizes methyltrichlorosilane (MTS) as precursor, acting as both carbon and silicon source, ...
  • Spheroidisation of iron powder in a microwave plasma reactor 
    Van Laar, Jean H.; Van der Walt, I.J.; Bissett, H.; Barry, J.C.; Crouse, Philippus L. (Southern African Institute of Mining and Metallurgy, 2016-10)
    Plasma-assisted spheroidisation of metal powders offers several technical advantages with respect to both the ease of materials handling and powder-metallurgical item manufacturing. Advantages include improved flowability, ...
