Tungsten Disulfide Nanopowder Description

Tungsten(IV) sulfide is a chemical compound with the formula WS2. It occurs naturally as the rare mineral called tungstenite. This material is a component of certain catalysts used for hydrodesulfurization and hydrodenitrification. WS2 adopts a layered structure related to MoS2, with W atoms situated in a trigonal prismatic coordination sphere.

Tungsten Disulfide Nanopowder Properties

WS2 nanoparticles are a very good performance of new solid lubricant materials, not only for general lubrication, but also it can be used in the work environment of high temperature, high pressure, high vacuum, high load, and with radiation and corrosive media; WS2 cluster within the cluster produce magnetic alignment, lubrication process can be better adsorbed on the metal surface to form a layer of nano protective lubricating film; WS2 has a very small friction coefficient (about 0.03), therefore it can be used as additives in the metal powder to obtain a stable friction coefficient; nanoscale WS2 has good resistance to oxidation, it can be used as additives to lubricating oil (grease) effectively to improve lubricants (grease) and extreme pressure properties and antiwear properties; Adding nanoscale WS2 In the casting process can make cast metal have a certain self-lubricating property and have an excellent adsorption capacity on the metal surface.

FAQs

Q1: What makes Nano WS2 Powder an effective lubricant?

A1: Nano WS2 Powder is highly effective as a lubricant because of its unique layered structure, similar to graphite. Each layer of WS2 can slide over one another easily, resulting in a low friction coefficient. The nano-sized particles provide better coverage and lubrication performance, even in extreme conditions such as high pressures or temperatures.

Q2: What are the storage conditions for Nano WS2 Powder?

A2: Nano WS2 Powder should be stored in a dry, cool environment to prevent moisture absorption or contamination. It is recommended to store the powder in a sealed container to maintain its purity and prevent oxidation or degradation of the material.

Q3: How is Nano WS2 Powder used in lubrication applications?

A3: Nano WS2 Powder is used as a dry lubricant in applications where traditional liquid lubricants may not be suitable, such as in high-temperature or vacuum environments. It can be applied directly to the surfaces of components or incorporated into lubricating oils and greases to improve their performance.
