Why Tungsten Wire Can Be for Photovoltaic Purpose by Replacing Carbon Steel Wire? 249

As one of the core consumables in the silicon wafer cutting process, the cutting effect of diamond wire is mainly affected by factors such as product thickness, busbar performance and cutting method. Generally speaking, the cutting effect is better when the diamond wire is thinner. Nowadays, the most common diamond wire busbar in the photovoltaic industry is high carbon steel wire, according to Chinatungsten Online. However, with the development of silicon wafers in the direction of large size and thinning,…

Manufacturing Processes of Thoriated Tungsten Wire Used in Microwave Generator 403

Magnetron, also known as microwave generator, magnetron microwave tube, is a kind of electronic tube, mainly composed of two parts: tube core and magnet. The tube core is composed of a filament, a cathode, an anode and a microwave energy output device. The filament, made of thoriated tungsten wire (ThO2 wire) or pure tungsten wire wound into a spiral shape, is used to heat the cathode. In order to improve the stability of magnetron emission, it is required to carbonize…
