摘要
氧化镁膨胀量的计算模型大都为经验性公式,在应用上具有局限性.为此,从化学反应的基本性质出发,推导了氧化镁膨胀的动力学模型.该模型既符合化学反应的一般规律,又能很好地吻合试验数据,可很好地模拟经历任意温度过程的氧化镁的膨胀量.
At present there are many models that calculates expansion of MgO, but none of them really reflects the effect of temperature on expansion. This paper analyzes their defects respectively, and deduces expansion model of dynamics for the first time. This model reveals the truth behind chemical changes and simulates experimental data quite well, it solves the problem of calculating MgO expansion enduring any temperature process exactly.
