钼丝和钼箔广泛用于白炽灯作冷却芯杆、灯丝支架和箔封。掺杂钼具有很高的高温强度和再结晶温度,高温应用中已大量取代未掺杂的钼材。掺杂铝-钾-硅(AKS)的钼由于细小钾泡对晶界的钉扎作用,再结晶温度可达1800℃(未掺杂的钼仅为1200℃),而氧化镧掺杂的钼,再结晶温度更高。为了弄
Molybdenum wire and molybdenum foil are widely used in incandescent lamps for cooling core rods, filament holders and foil seals. Doping molybdenum has a high temperature strength and recrystallization temperature, a large number of non-doped molybdenum material has been replaced in high temperature applications. Doped aluminum-potassium-silicon (AKS) molybdenum due to small potassium bubble on the grain boundary pinning effect, recrystallization temperature up to 1800 ℃ (undoped molybdenum is only 1200 ℃), and lanthanum oxide doped molybdenum , Recrystallization temperature is higher. To get it
