Engineering Research Equipment: High Pressure Technology inNoncatalytic Reaction Engineering Problems

该设备拨款用于购买高容量、高温、中压（200atm）的装置，PI将在其中生产先进的陶瓷材料。同时，通用电气公司向这个研究小组捐赠了几个小体积、高温、高压（80000 atm）的装置，从而建立了一个可行的核心设备，用于研究制造这些材料所需的最佳反应条件。纽约州立大学布法罗分校正在为PI提供额外的空间，以加强整体努力，使其成为世界级的实验设施。高级陶瓷与传统陶瓷的区别在于它们所具有的特殊性质以及它们所需要的复杂加工。先进陶瓷材料的一些例子是氮化硅（Si3N4），碳化硅（SiC）和氮化铝（AlN），它们可能有许多用途，例如作为电子和光学设备的耐热和耐磨部件。PI开发了一种新的概念，利用强放热反应释放热量，在很短的时间内在单个反应器中进行高温，高压，自传播同时合成和烧结。他还在研究不同陶瓷材料或陶瓷与金属之间的键合新概念，特别是将氮化硅、氧化铝和陶瓷材料与钼和不锈钢键合。这种特殊的设备将用于较大尺寸的样品（例如6“x 6”x 2”），例如TiB2和SiC管的焊接，Mo片的焊接，Si粉在N2中的燃烧等。

This equipment grant is for the purchase of a high volume, high temperature, medium pressure (200 atm) unit in which the PI will produce advanced ceramic materials. Simultaneously, General Electric is donating several small volume, high temperature, high pressure (80,000 atm) units to this research group thus establishing a viable core of equipment for the study of optimal reaction conditions needed for the manufacture of these materials. SUNY-Buffalo is providing additional space to the PI to enhance the overall effort and make this a world-class experimental facility. Advanced ceramics are differentiated from traditional ceramics by the specialized properties they posses as well as by the sophisticated processing they require. Some examples of advanced ceramic materials are silicon nitride (Si3N4), silicon carbide (SiC) and aluminum nitride (AlN) and they might have many uses for example as heat - and wear-resistant parts to electronic and optical devices. The PI has developed a new concept for high-temperature, high-pressure, self-propagating simultaneous synthesis and sintering in a single reactor in a very short period of time utilizing the liberation of heat by the strongly exothermic reactions involved. He is also looking at a new concept for bonding between different ceramic materials or ceramics and metals, specifically bonding silicon nitride, aluminum oxide and ceramic materials to molybdenum and stainless steel. This specific apparatus will be used for samples of larger dimensions (e.g. 6" x 6" x 2") such as welding of TiB2 and SiC tubes, welding to Mo sheets, combustion of Si powder in N2, etc.
