Hot Pressing (RHP) Study

  • Akshoy Kumar Chakraborty
Chapter

Abstract

Hot pressing characteristics of clays have been done for the following aspects. (i) In achieving high density of the products; (ii) To reveal the mechanism of densification; (iii) To study the mineralogical changes in comparison to normal phase change taking place during usual heating. RHP was first noted by Hedvall (1938) and is commonly called “Hedvall effect.” Pressure is applied during a phase change where there is enhanced reactivity and consequently it assists densification.
