- 介绍: 钛酸钡晶体有这样的特性:当它受压力而改变形状的时候,会产生电流,一通电又会改变形状。于是,人们把钛酸钡放在超声波中,它受压便产生电流,由它所产生的电流的大小可以测知超声波的强弱。相反,用高频电流通过它,则可以产生超声波。现在,几乎所有的超声波仪器中,都要用到钛酸钡。除此之外,钛酸钡还有许多用途。例如:铁路工人把它放在铁轨下面,来测量火车通过时候的压力;医生用它制成脉搏记录器。用钛酸钡做的水底探测器,是锐利的水下眼睛,它不只能够看到鱼群,而且还可以看到水底下的暗礁、冰山和敌人的潜水艇等。
- 熔点: 1625°C
- 用途: 主要用于电子陶瓷、PTC热敏电阻、电容器等多种电子元器件的配制。
