16. Sintering of cemented carbides : experiments and modeling
Abstract : During sintering of cemented carbides large volumetricshrinkage takes place. About half the volume of the originalgreen body is lost during this process. Due to lotal densitydifferentes within the green body undesired shape changes mayalso occur during sintering. READ MORE

17. Novel powder-coating solutions to improved micro-structures of ZnO based varistors, WC-Co cutting tools, and Co/Ni nano-phase films and sponges
Abstract : Solution chemistry is a versatile and powerful tool in the synthesis of designed, complex nano-level high-tech materials. Normally, the technique is considered too expensive for large-scale production of complex multi-component ceramic materials. READ MORE

18. Synthesis and Characterization of Nitrogen-rich Calcium α-Sialon Ceramics
Abstract : In this thesis, a synthesis concept has been developed, which uses nitrogen-rich liquid phases for sintering of Ca-α-sialon ceramics. First, keeping the Si/Al ratios constant, the effects of N/O ratio on the properties and microstructure were investigated through a liquid phase sintering process. READ MORE

20. Preparation and characterisation of refractory whiskers and selected alumina composites
Abstract : A whisker is a common name of single crystalline inorganic fibre of small dimensions, typically 0.5-1 μm in diameter and 20-50 μm in length. Whiskers are mainly used as reinforcement of ceramics. This work describes the synthesis and characterisation of new whisker types. READ MORE
