摘要
给出了钼及其化合物的4种新用途。钼的同位素99Mo及其衰变后的"孪生"元素99mTc在癌症的诊断等医疗诊断流程中显示出极其重要的作用。Mo S2作为新一代半导体材料使半导体芯片厚度降低2/3,储用功率可降低10万倍,极大地促进集成电路的微型化和异型化。Mo2C和Mo2N作为催化物的基底材料,可有效提高催化物的比表面积,Mo2C和Mo2N基催化剂在制氢和制烃的反应中具有强烈的催化作用。Mo-Mo2C等离子喷涂技术在活塞环表面形成具有一定韧性的致密涂层,远优于钼金属火焰喷涂效果,涂层使用寿命可达到150 000 km。
Four emerging applications of molybdenum and its compounds are presented. The molybdenum isotope Mo- 99 and its decay cousin Tc- 99 m are extremely helpful and show great promise in medical procedures,for example in the diagnosis of cancer. As the next semiconductor material,MoS2,in single- layer form,would make chips three smaller than using silicon,and reduce standby power demand by a factor of 100,000 compared to current silicon- based technology,leading to smaller electronic device with flexible shapes. By depositing catalytic metals on Mo- based surface,catalytic compounds based on Mo2C and Mo2N showed encouraging potential in chemical processes that produce hydrogen and hydrocarbons. Prepared by plasma- sprayed technology,compound coating of Mo and Mo2C provide excellent toughness and sealing efficiency,making piston rings deliver much greater wear resistance and better overall performance than flame- spayed rings coated with pure molybdenum.
