Preparation process of high-temperature-resistant ceramic aerogel based on nanotechnology
A high-temperature-resistant ceramic aerogel preparation process based on a nanotechnology comprises the following steps that a ceramic powder mixture is suspended in a solvent, appropriate ceramic materials such as aluminum oxide and zirconium oxide are selected as base materials, and the materials have high melting points and good high-temperature resistance and cannot be diffused; then common preparation methods comprise a sol-gel method, a hydrothermal method and the like, the sol-gel method is a relatively common preparation method, ceramic gel is formed through sol gelatinization and subsequent heat treatment, then the selected ceramic base material is dissolved in a proper solvent, uniform sol is formed, and the sol-gel ceramic base material is prepared. Common solvents comprise water, alcohol solvents and the like so as to eliminate residual solvents and realize hardening of ceramic gel, and in the heat treatment process, the ceramic gel can generate various chemical and physical changes to gradually form a formed ceramic material.
一种基于纳米技术的耐高温陶瓷气凝胶制备工艺，按照如下步骤进行:将陶瓷粉体混合物悬浮于溶剂中，选择合适的陶瓷材料作为基础材料，例如氧化铝、氧化锆等，这些材料具有较高的熔点和良好的耐高温性能，使其不会散发，然后常用的制备方法包括溶胶‑凝胶法和水热法等，其中，溶胶‑凝胶法是较为常用的制备方法，它通过溶胶的凝胶化及后续热处理，形成陶瓷凝胶，接着将所选的陶瓷基础材料溶解在适当的溶剂中，形成均匀的溶胶，常用的溶剂包括水、醇类溶剂等，以消除残余的溶剂和实现陶瓷凝胶的硬化，热处理过程中，陶瓷凝胶会发生多种化学和物理变化，逐渐形成成型的陶瓷材料。
