MoILQ is a microdoped molybdenum alloy with a lanthanum oxide content of only 0.03 percent by weight which has been specially developed for use in the lighting industry. Thanks to its specially adapted dopant content, its recrystallization temperature is higher than that of pure molybdenum. After recrystallization, its microstructure is also more fine-grained than in the case of pure molybdenum. Compared to other ML materials, MoILQ is more suitable for forming and therefore easier to process.
