Best Price for Tungsten Alloys Tubing - E-Beam Filament 7.5turns – WINNERS Detail:
Product Description
▎Product parameters
The choice of materials has a decisive influence on the emission ability and life of the electron gun. Filament must be made of high melting point and high resistivity material, generally made of tungsten wire. After passing through the strong current, the filament is heated to more than 1000 degrees. The cathode must be made of a low work function material. The outer electrons of the atoms on the cathode surface, after being excited by a certain amount of heat or electrical energy, will detach from the nucleus and become free electrons. Tungsten wire is selected as the material, and its work function is 4.55 electron volts. When the working temperature is 2500K, J = 0.5A / cm². The melting point of tungsten wire is 3655 K. When the working temperature is 2750 K. The evaporation rate is 0.0043mg / cm·s, and the corrosion resistance of tungsten wire is strong.
