The E ffect of T emperature on F low P roperties of F ine P owders

Many works in literature investigated the effect of the increasing temperature on powders in fluidization conditions (Formisani et al., 2002) but very few studies concern with the analysis of the powder flow properties at high temperature by means of conventional testers and procedures commonly employ ed at ambient conditions, i.e. uniaxial tester and shear cell. However, the effect of the temperature on powder flow properties has been often interpreted by assuming t he presence of softening and sintering phenomena of the particles affecting the int rparticle forces (Kamiya et al., 2002).
