Liquid Phase Processing & Synthesis at Very High Temperatures

该项目探索陶瓷、超导体和金属的无容器液相加工。这一过程本身被称为“AAL”，或气声悬浮。二氧化碳激光器将颗粒加热到2700摄氏度。第一阶段展示了陶瓷和玻璃的AAL工艺。第二阶段的工作包括三个部分：(1)悬浮过程的表征；(2)材料加工的自动化：(3)合作研究。这些步骤是将AAL应用于感兴趣的材料、准备大量材料和评估加工材料所必需的。AAL工艺的前景看好的应用包括生产具有商业潜力的高附加值材料。晶体、纤维和非平衡合成的新方法应该是可能的。

This program explores containerless liquid phase processing of ceramics, superconductors, and metals. The process itself is referred to as "AAL", or aero-acoustic levitation. A CO2 laser heats the particle up to 2700 degrees C. Phase I demonstrated the AAL process for ceramic and glass. The work in Phase II has three parts: (1) characterization of the levitator process; (2) automation of the processing of materials: (3) collaborative research. These steps are required to apply AAL to materials of interest, prepare quantities of materials, and evaluate the processed materials. %%% Promising applications of the AAL process involve the production of high value-added materials with commercial potential. New methods for crystal, fiber, and non-equilibrium synthesis should be possible.
