| Abstract: |
| In order to realize the formation of the complicated ceramic components at frozen temperature with low cost, this paper investigates the effects of Al2O3 ceramic paste formulation on its forming process and physical and mechanical properties. Central composite design (CCD) is used to design the experiments to observe the impacts of the pH value, binder and dispersant factors on the alumina ceramic paste viscosity. The process parameters which can impact the alumina ceramic paste viscosity are analyzed using the response surface method (RSM). The response model for viscosity of alumina ceramic paste is developed, and a function of satisfaction (DFM) is used to determine the optimal process parameters. The experiment results show that the model is able to predict the viscosity values responsibly. |
