日本东京工业大学大学院的小田原修副教授等,采用在液氮浴中的钛压块的下部表面上加热着火,伴随向压块上方的反应传播而使气相成分及热也向压块上方移动的方法制成高纯氮化钛。该项新技术是将金属钛压块置于充填有液氮的反应器中,在钛压块的下部端面配置有耐热性导体,对导体通电,使压块的下部表面的一部分加热至1700℃以上而诱导压块与氮的燃烧反应,然后压块与氮开始相互作用,因燃烧产生的热而形成的2000℃以上的高温反应层以层状形式逐次向压块上方进行,从而制成高纯的氮化钛。新技术的特点是:1.由于从试料下部着火,控制了反应从试料下部向上部传播,使其与因发热反应而
Japan Tokyo Institute of Technology, Associate Professor Odahara repair, etc., using the liquid nitrogen bath in the lower surface of the titanium briquette heating fire, along with the reaction pressure above the propagation of the gas component and the heat is also moving above the briquette method Made of high purity titanium nitride. In the new technology, a titanium metal block is placed in a reactor filled with liquid nitrogen. A heat-resistant conductor is arranged on the lower end surface of the titanium block, and electricity is applied to the conductor to heat a part of the lower surface of the block to 1,700 ° C or more to induce a combustion reaction between the compact and the nitrogen, and then the compact starts to interact with the nitrogen, and a high-temperature reaction layer of 2000 ° C or higher formed by the combustion heat is sequentially carried out in a layered form over the compact, High purity titanium nitride. The new technology is characterized by: 1. Since the lower part of the fire from the sample, control the reaction from the lower part of the sample to the upper part of the spread, so that due to fever and reaction
