How to prepare tungsten disulfide nanoparticles? At present, the flower-shaped WS2 nanoparticles are mainly prepared by hydrothermal method. While this method has the disadvantage of low yield, which is not conducive to mass production. So, some experts have proposed a simple process - high temperature vulcanization method - to prepare flower-shaped WS2 nano particles. The high purity WS2 nano particles are prepared by this method with low cost and high yield, so it is expected to be used in large-scale industrial production.

Tungsten disulfide catalyst has excellent dispersibility and catalytic activity in both polar and non-polar catalytic reaction systems. Some experts formulate the tungsten source, sulfur source, reducing agent, ionic liquid and deionized water into the initial reaction mixture in a certain order and method, and then crystallize it under hydrothermal conditions in a sealed high-pressure reactor. After filtering, washing and drying the crystallized product, a tungsten disulfide catalyst is obtained.

Tungsten disulfide lubricant, which is made from solid tungsten disulfide (WS2), lubricating oil and other components, has a wide temperature range, excellent anti-extreme pressure performance, anti-corrosion performance, anti-radiation performance and other comprehensive performances, so that it can fully meet the demanding use requirements, such as high temperature, vacuum environment and large load. Also, such a lubricant can be used to lubricate various mechanical equipment in corrosive environments where requiring increasing load and decreasing friction coefficient.

Tungsten alloy underwater bullet is a specially designed tungsten alloy bullet with large aspect ratio and excellent performance for applications of underwater rifles and underwater submachine guns. It means that the warhead of the tungsten alloy bullet for underwater firearms is slender, and therefore its effective range is far from that of ordinary bullets. Tungsten alloy warhead of such a bullet looks like a needle.

Tungsten alloy core armor-piercing bullet is a new type of armor-piercing projectile developed to replace the depleted uranium projectile. Compared with toxic and radioactive depleted uranium shells, tungsten alloy core armor-piercing projectiles is an environmentally friendly weapon. Moreover, the armor-piercing projectile using tungsten alloy as the core material has the advantages of high speed, large kinetic energy, low trajectory, short flight time, high hit accuracy, and large armor-piercing power. In a word, the overall performance of tungsten alloy projectiles is not worse than that of depleted uranium projectiles.

Tungsten alloy armor may be used as the armor for aircraft, tanks and other military vehicles to defend against physical attacks of a certain energy including kinetic energy, thermal energy, electromagnetic radiation, etc., to reduce the enemy's damage to our military targets.

Tungsten alloy underwater rifle bullet is designed with a long warhead. Well, do you know why tungsten alloy underwater rifle bullet is so long? You know, human ancestors can make bamboo, wood, or metal into spear-like weapons thousands of years ago. And they quickly projected these spears into the water to catch fish.

Although tungsten alloy underwater assault rifle bullet looks like a nail, it can make the underwater rifle have a longer range and higher penetration than the fishing gun. Under water, the resistance encountered by the warhead "flying" is completely different from the air resistance it encounters when flying in the air, so whether the bullet is shot into the water from the air or underwater, bullets consume a lot of kinetic energy due to water resistance and water pressure, resulting in a sharp reduction in range.

Tungsten alloy underwater automatic rifle bullet having high aspect ratio is a kind of special bullet for using underwater. You know, the underwater automatic rifle is an underwater weapon specially developed for fighting frogmen, and has always been a field highly valued by various countries. As an important killing component of underwater rifles, the research and development of bullets is of great importance.

Tungsten alloy bullet has advantages of strong penetrating power, high hit rate and good toughness as the warhead of the bullet is made of high-quality tungsten alloy that has characteristics of high density, high strength, high hardness, small thermal conductivity, small thermal expansion coefficient, and good mechanical processing performance, oxidation resistance and corrosion resistance. Tungsten alloy can be processed into large-diameter or small-diameter warheads.
