Description of Tungsten Disilicide Powder
Tungsten Disilicide Powder (WSi2) is a fine, gray powder composed of tungsten and silicon in a 1:2 atomic ratio. It is a refractory material, meaning it has a high melting point and excellent thermal stability, making it suitable for high-temperature applications.
Tungsten Disilicide Powder Should be handled with care to avoid inhalation or ingestion. Protective equipment such as gloves, masks, and goggles should be used. It needs to be stored in a cool, dry place to prevent oxidation or degradation over time.
Princeton Powder is a leading supplier of Tungsten Disilicide Powder powder. It is fro sale at a competitive price.
