2. Liquid phase sintering of W-Ni-Fe composites : liquid penetration, agglomerate separation and tungsten particle growth
Abstract : The initial stage of liquid phase sintering, involving liquid penetration, agglomerate separation, particle spreading and growth has been investigated in experiments using tungsten heavy alloys. The particle composites used were produced by hot isostatic pressing (HIP) of pure powder mixtures of W-Ni-Fe-(Co). READ MORE

3. Separation of plastics by flotation
Abstract : This thesis analyses and summarises the importance of plastics waste recycling and plastics waste separation, presents an innovative principle for plastics flotation, and provides various methods for the separation of plastics mixtures. The objective is to understand the mechanisms for selective flotation separation of plastics, get plastics mixtures separated and enable more plastics wastes to be recycled. READ MORE
