    Dec 28, 2015  The origin of sintering process goes back to 1887 when F. Haberlein and T. Huntington of England invented the process of agglomeration for sintering of sulphide ores. In this process, the sintering was carried with the sintering bed being blown with air from bottom upwards. The process was also known as up-draft sintering process.

    Feb 27, 2008  Three methods enlarge particulate solids through agglomeration: tumble/growth agglomeration, pressure agglomeration, and agglomeration using heat (sintering). In tumble/growth agglomeration, the adhesion of particles to one another is controlled by the competition between volume-related separation and surface-related adhesion forces.

    Granulation is the process of agglomeration of powder materials and has been widely used in chemical, pharmaceutical, and food industries to process, store, and transfer powder materials. In a conventional granulation method, a volatile solvent is usually used to bind the powder particles into granules, and then is removed by drying.

    Firn densification is an analogous process to pressure-sintering or hot-pressing in ceramics, where an assemblage of particles is compacted at high temperature and pressure. Firn naturally exists at temperatures close to its melting point, and experiences increasing pressure with depth due to accumulating snow layers at the surface.
