Abstract

The freeze-dry process and its application in the general area of inorganic materials synthesis will be discussed. Details of the process will be given as well as its capabilities for producing ultrafine powders such as Pb–10 v/o MgO, WC, and W2C, ultrafine grained consolidated materials such as W–25 Re will be shown. Also, the application of the process for producing dispersion-strengthened systems such as Cu–ThO2 and Cu–W will be discussed.
