The Thermodynamics And Dynamics Research Of Decomposition Potassium Feldspar In Low Temperature

This thesis mainly researchs the response mechanism of decomposing the potassium feldspar in the low temperature from theory. First, research of thermodynamics, through experiment and calculation, judging the possibility of the reaction' s taking place, Analyse and judging from several following respects: Calculation of Δ_rG_m~0; Under the standard state, different concentration and partial pressure , 150 degrees Centigrade, the Calculation of Δ_rG_m; the calculation of Balance constant and influence factor and discuss; Setting-up of the thermodynamics model; Discussing feasibility and stability of the reaction; Draw separately Δ_rG_m~T picture, Δ_rG_m~C picture, Δ_rG_m~P picture, judging the feasibility of the reaction that happens. Second, the research of dynamics, through the experiment under different conditions , founding the best response condition and realizing the anticipated purpose of thermodynamics, There are the following several respects mainly: Using isolation method and differentiation determines the response progression that reacts; the influence of temperature to the speed of response and discussing; the activation enegy calculation ; the grain size's influence on the speed of response ; Setting-up of the dynamics equation; Find out the best response condition.
