These are referred to as “refractory metals”, ie tungsten, molybdenum, niobium, tantalum, rhenium, zirconium and Hafnium, etc., which are crucial for the current variety of industrial light sources. Do not dip potassium doped tungsten wire and tungsten coil is an indispensable part of a variety of industrial incandescent lamp materials. From the solid material technology point of view, halogen
