Equation of Shrinkage Rate of Al2O3 Determined by Sinter-Forging

摘要: The sintering rate for the initial stage of was expressed as a function temperature and relative density two kinds Al2O3 which differ in purity mean particle size. Parameters equations were determined by experiments under uniaxial load. After it confirmed that remarkable grain growth not observed range this experiment, determined. Calculated gave fairly good agreement with experimental data. Change during calculated compared difference between values data remained less than 2% all cases. It became evident change able to predict equation based on visco-elastic analogy model.
