Lanthanated tungsten electrodes Firmetal Co., Ltd.

The most common lanthanum tungsten electrode contains 1% lanthanum oxide (La203), known as lanthanum oxide. In Europe and Japan, lanthanum tungsten electrodes have been the most commonly used alternative to thorium tungsten electrodes in most applications. There are 3 kinds of lanthanum oxide, lanthanum oxide 1.5% and lanthanum oxide 1%.

Thorium Dioxide an overview ScienceDirect Topics

Thorium is radioactive, giving off both alpha and gamma radiation. Employers should consider the use of an alternative, thorium free electrode, to reduce the risk from radioactivity. Bulk supplies of thoriated tungsten electrodes should be stored in a metal cabinet or box, labelled to indicate the contents.
