                              Description: 
                              A 99.9% pure silver grey powder composed of flaky particles of tungsten disulfide.
Typical Use: 
                              - Lubrication: the lubricating properties of these particles make them extremely valuable, especially in more rigorous environments with high pressure, extreme weights, or strong vacuums.
 - Composite materials: various composite materials can be produced using tungsten disulfide particles, benefiting from its lubricating, semiconducting, and resilient properties.
