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.

这项设备赠款是为购买一个高容量，高 温度，中压（200 atm）单位，其中PI将 生产先进的陶瓷材料。 与此同时，通用电气 是在高温高压下， (80 000个大气压），从而建立了一个可行的 研究最佳反应条件所需的核心设备 用于制造这些材料。 纽约州立大学布法罗分校提供 为PI提供额外的空间，以增强整体工作，并使其 世界级的实验设施 先进陶瓷是 区别于传统陶瓷的特殊性能 它们不仅需要复杂的加工过程， 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），并且它们 可能有许多用途，例如作为耐热和耐磨部件， 电子和光学器件。 PI开发了一个新的概念 用于高温、高压、自蔓延同时 合成和烧结在一个单一的反应器在很短的时间内， 利用强放热反应释放热量的时间 涉及的反应。 他还在研究一种新的结合概念 在不同的陶瓷材料或陶瓷和金属之间， 特别是结合氮化硅、氧化铝和陶瓷 材料钼和不锈钢。 这个特殊的装置 将用于较大尺寸的样品（例如6”x 6”x 2”）， 如TiB2和SiC管的焊接、Mo片的焊接、 氮气中的Si粉等。
