制造微波管的新型材料金刚石正进入实用阶段氧化铝、氧化被、氮化硼和氮化铝由于在绝缘与导热性能方面的特长，一直是制造各类微波器件必不可缺的材料。然而，不久这些材料将有可能被一种新材料──金刚石所取代。英国ＴＭＤ公司的研究人员发现，用化学汽相沉积方法制成的... New material for making microwave tubes Diamonds are entering the practical stage Alumina, oxide, boron nitride and aluminum nitride have been indispensable for the manufacture of various types of microwave devices due to their superiority in insulation and thermal conductivity. However, in the near future these materials will likely be replaced by a new material, diamond. British TMD researchers found that the chemical vapor deposition method made ...
