Spray Drying. Technology Volume One Editors M.W.Woo, A.S. Mujumdar, W.R.W. Daud Preface Spray drying is a ubiquitous industrial operation found in numerous industrial sectors. It is employed to produce engineered powders from liquid feedstocks in a single step. Extensive research and development efforts in understanding the fundamentals and applications of spray drying in recent years has
Learn MoreThe invention discloses a tungsten-aluminum alloy and a preparation method for the same. The method sequentially comprises a raw powder preparation step, a cold isostatic pressing forming step, a hot isostatic pressing blank preparation step and a hot isostatic pressing sintering step. According to the tungsten-aluminum alloy and the preparation method for the same, conventional W and Al
Learn MoreFor indirect ceramic additive manufacturing (AM), green parts' initial densities are low, limiting the postprocessing strengthening under atmospheric pressure. This study employed binder jetting printing (BJP) based on the polycondensation curing of urea-formaldehyde resin to produce series of Al 2 O 3 green specimens with controllable structures.
Learn MoreThe purpose of this handbook is to provide, in condensed form, technical information and data of direct usefulness to design engineers. The numerical values for properties listed in this handbook have been checked for suitability for use in design. Wherever practicable, the various types, classes, and grades of materials are identified with applicable government specifications.

The lattice parameters for both spinel Fig. 1 depicts the decrease in apparent porosity and apparent specific gravity as the firing temperature is
Learn MoreSelective Laser Sintering (SLS) is an Additive Manufacturing process that belongs to the Powder Bed Fusion family. In SLS, a laser selectively sinters the particles of a polymer powder, fusing them together and building a part layer-by-layer. especially for small batch productions. A bin of a given height will take about the same time to

Learn MoreSintering was performed in a laboratory "batch" furnace at temperatures in the range 2050 ° F to 2300 ° F (1120 to 1260 ° C), mainly in a pure hydrogen atmosphere. A limited part of the study was completed using a 75 v/o H 2 / 25 v/o N 2 atmosphere. The time at sintering temperature was maintained at thirty minutes.
Learn Moresintering. Sintering schedule was varied from batch to batch. Here, sintering is carried out at 1175 °C, 1200°C and 1225C in air atmosphere. However, for every sintering schedule all samples with similar composition were put in the furnace at the same time. X-ray diffraction experiments were performed after the powders
