PROBLEM TO BE SOLVED : rare metals other than nickel (for example, molybdenum (Mo), niobium (Nb), vanadium (V), titanium (Ti), zirconium (Zr), hafnium (Hf), chromium (Cr), or the like) without using substantially, and deep-drawing and sputtering resistance both to provide an electrode for a cold-cathode discharge tube. SOLUTION : contg. amt. 17. More than 0% by mass 23. 0% by mass or less of iron (Fe) of contg., nickel (Ni) and the balance of inevitable impurities alloy is used for the cold cathode discharge tube. Selected drawing : no |
