About Tungsten Disulfide WS2: Tungsten disulfide This organic compound is made of both sulfur and tungsten. Tungsten disulfide chemical formula It is WS2 . It belongs to the Transition-Metal Dihalides. It's the rarest type of tungsten. This material is part of certain catalysts used for hydrodesulfurization and hydrodenitrogenation. WS2 tungsten disulfide It has a similar structure to MoS2 and is also a type MoS2; replaces MoS2’s coordinatesphere by Watoms. The three are enclosed within a triangular prism. This layer structure was heated to form inorganic nanotubes (W2) following 1992. Many WS2 Crystals have dark gray hues and are hexagonal. Layered WS2 Crystals may also be observed. The WS2Crystal is an oillubricant similar to MoS2.
Many people believed that WS2 would not be affected by ambient oxygen. Studies on single-layer, environment-dependent WS2 oxidation have revealed that the contrary is true. By photooxidation, one layer of the WS2 can be quickly transformed into tungstenoxide. You can perform the photooxidation reaction under both ambient and atmospheric conditions. Photooxidation is the absorption and oxidation of visible light at 660nm/>1.88eV by WS2. Only water and oxygen can cause the reaction. It will produce tungsten dioxide and sulfuric acids. Similar results were obtained for semiconductor transitional métallique dihalides (e.g. MoS2) when they were exposed at ambient light.
Combining hydrofluoric and nitric acids can attack WS2. In oxygen rich areas, WS2 may turn to tungsten dioxide if heated. The problem is that the WS2 won't melt when heated. It will instead decompose to tungsten dioxide. WS2 melts at 1250oC.
Monolayers WS2 have been removed using chemical exfoliation in the past. The process involves placing lithium in Hexane, then applying ultrasonics the Li compound. To get rid of the WS2, you can use different agents, such as chlorosulfonic and lithium halide.

It's simple. Tungsten Disulfide WS2 produced?
1. Roasting decomposition method:
Stir the mixture constantly for three hours in a temperature of 57 to 60 degrees Celsius. For 16 hours, keep the mixture at room temperature. The ammonium and hydrogen sulfuride gases react to make ammonium-tungstate. The result is Ammonium Tetrathiotungstate. The heat treatment of the ammonium Tetrathiotungstate can make it tungstenoxide.
2. Tungsten is slow to react with liquid sulfur. You can turn the sulfur-vapor color from red hot to make WS2. Mixing tungsten can produce WS2. Orthorhombic compounds may be formed by reacting at 1600pa or 600pa.
3. By heating the ammonium-tetrathiotungstate and decomposing it, under the condition that the air is isolated, the temperature increases from room to 700 to 1200. It is kept at ambient temp for 24 to 48 hours before being decomposed. The temperature then drops to ambient with a temperature gradient of 30-110degC/hour. It will reach a temperature gradient of 30-110degC/hour after being kept at room temperature between 24-48 hours and decomposing it.
Ultrafine and fine tungsten dioxide is produced by this process. The process doesn't have any impact on the environment.

Applicaciones Tungsten Disulfide WS2:
Tungsten disulfide
It's possible. tungsten disulfide lubricant, tungsten disulfide grease.
Tungsten Disulfide2W2 has a friction film coating that is extremely smooth and dry. Tungsten Dioxide (WS2) is 0.03 in friction coefficient. This makes it more effective than graphite (PTFE), graphite[MoS2], graphite[MoS2], graphite[MoS2], graphite[MoS2], graphit,,MoS2 ). It's highly lubricious. This powder can be used in the manufacture of electronic equipment like transistors or sensors. Mix this powder with alcohol and water.
You can use WS2 to extrude, mold plastic and other types of molding.
It does not require hydraulic oil. It can be combined with synthetic oil, grease or other oils. Due to its ability to stick with fluid layers, it is able preserve them. The surface is protected from oil and grease. This improves the quality of the lubrication.
Tolerances are possible on parts with a diameter less than 1 millimeter.
Additionally, the WS2 is useful for maintaining medical equipment and cooking.
Base materials can be replaced by WS2 at ambient temperatures. It doesn't make the substrate inconstant or unstable.
You can increase durability by combining WS2 with PVD hard coat.

Tungsten Disulfide Powder Storage Conditions:
The air should be kept out of the reach and control of tungsten dioxide. Dampness could also impact the dispersion of WS2 powder. Use WS2 Powder with caution.

Packing and Shipping Tungsten Disulfide WS2 Pulver:
You can package Tungsten dioxide W2 powder in many different ways depending on its size.
Tungsten Disulfide Powder Packaging: vacuum packing 100g to500g at 1kg/bag @ 25,5kg/barrel. Other options can be requested
Tungsten diulfide Powder Shipping: After payment receipt received, can ship via sea or air.
