Description

This special Tungsten Lanthanum Oxide (WL) was specifically developed for use in the stems (support rods) of high-pressure discharge lamps. A special production process is used to create a more fine-grained microstructure than is found in standard quality tungsten-lanthanum oxide. Thanks to this special microstructure, the breaking strength of the material is higher than that of standard quality WL and WVM even following exposure to high thermal loads.
