据日报《日经产业新闻》报道,氮化铝是一种高温强度大,且耐腐蚀性强,导热性和电绝缘性优异的材料。已开始用它制作熔融金属的坩埚和烧结炉夹具等各种耐高温制品,人们希望它今后能应用于集成电路基板和散热性电子元件等领域。同氮化硅、氮化硼一样,根本不存在天然的氮化铝,必须人工合成。由于氮化铝离子键性很强,在高压下加压烧结,能得到高密度的烧结体。可是,热压烧结氮化铝时,即使使用
According to the daily “Nikkei Industrial News” reported that aluminum nitride is a high temperature strength, and corrosion resistance, thermal conductivity and electrical insulation excellent material. It has been used to make molten metal crucibles and sintering jig and other high temperature products, it is hoped that it can be used in the future, such as integrated circuit substrate and heat dissipation of electronic components and other fields. Like silicon nitride, boron nitride, there is no natural aluminum nitride, must be synthesized. Due to the strong ionic bond of aluminum nitride, pressure sintering under high pressure can produce high-density sintered body. However, even when hot-pressed aluminum nitride is used
