Why Tungsten Wire Can Be for Photovoltaic Purpose by Replacing Carbon Steel Wire? 229

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,…

Why Tungsten Crucibles and Molybdenum Crucibles Are Used for Sapphire Crystal Growth? 226

Crystal growth is the foundation of many cutting-edge technologies such as sapphire touchscreens, LED lighting components, solar cells and high-power lasers. Corrosion resistance, creep resistance and high temperature properties enable tungsten and molybdenum crucibles to be used for high temperature sapphire crystal growth processes. Crucibles made of tungsten and molybdenum materials perform well in the heat exchanger method (HEM) process for melting and solidification of single crystals. Better sapphire yield and quality can be achieved when the sapphire is easy…

Types of Molybdenum Crucibles Manufactured by Different Processes 193

Molybdenum is a refractory metal known for its excellent strength at high temperatures, high melting point of 2610 ℃, and high corrosion resistance. This high melting point makes molybdenum ideal for use as evaporation boats or crucibles, and for processing nuclear fuel pellets at temperatures up to 1650°C. products made of molybdenum are durable enough to withstand repeated rough handling. Molybdenum will not oxidize to any significant degree below 400 ℃ in air or an oxygen-containing atmosphere. At 400 ℃…
