二.理化性质 Physicochemical Properties

一般不溶于其他酸、碱、有机溶剂中，但溶于王水和煮沸的浓硫酸，有刺激性。密度4.80g/cm3（14℃），莫氏硬度1.0～1.5。熔点1185℃，1370℃开始分解，1600℃分解为金属钼和硫。315℃在空气中加热时开始被氧化，温度升高，氧化反应加快。

The product is generally insoluble in other acids, alkalis and organic solvents, but dissolved in aqua regia and boiling concentrated sulfuric acid with irritating. The density is 4.80g / cm3 (14 ℃); Mohs hardness is 1.0 to 1.5; melting point is 1185 ℃. The product begins to decompose at 1370 ℃ and decomposed into molybdenum and sulfur at 1600 ℃. It begins to be oxidized when heated in air at 315 ℃. When temperature rises, oxidation reaction will be speeded up.

三．产品用途 Application

1.制造钼化合物。

1. Used to manufacturing molybdenum compound.

2.润滑添加剂：二硫化钼是重要的固体润滑剂，特别适用于高温高压下。它也被被誉为“高级固体润滑油王”。 产品具有分散性好，不粘结的优点，可添加在各种油脂里，形成绝不粘结的胶体状态，能增加油脂的润滑性和极压性。也适用于高温、高压、高转速高负荷的机械工作状态，延长设备寿命。二硫化钼用于摩擦材料主要功能是低温时减摩，高温时增摩，烧失量小，在摩擦材料中易挥发;减摩：由超音速气流粉碎加工而成的二硫化钼粒度达到325-2500目，微颗粒硬度1-1.5，摩擦系数0.05-0.1，所以它用于摩擦材料中可起到减摩作用。

2. Lubrication Additive: molybdenum disulfide is an important solid lubricant,     especially applicable under high temperature and pressure. It is also known as   "King of advanced solid lubricants". The product has advantages of good        dispersion, non-stick, that can be added in various types of oils and fats and the formation of colloidal is never bonded. As a result, it can increase oil lubricity  and extreme pressure. The product is also suitable  for mechanical operation withhigh temperature, pressure, speed and loading, helping to extend equipment life. The main function of molybdenum disulfide for frictional materials is to reduce   friction at low temperatures and increase friction at high temperatures. There is small loss on ignition. The product can be easily volatile in friction materials.

Antifriction: Through the supersonic jet mill processing.  the particle size of molybdenum disulfide reaches 325 -2500 meshes; microparticles reaches 1-1.5 hardness, friction coefficient to be 0.05-0.1. Hence, it can reduce friction among frictional materials.

3.氢化反应和异构化反应催化剂：二硫化钼还可用作复杂烃类脱氢的催化剂。

3. Used as catalysts for hydrogenation and isomerization. Molybdenum disulfide is also used as catalysts for dehydrogenation of complex hydrocarbon.

4.它还有抗磁性，可用作线性光电导体和显示P型或N型导电性能的半导体，具有整流和换能的作用。

The product is anti-magnetic which can be used as the linear photoconductor and           semiconductor with display of P-type or N-type conductivity, having the rectifier and the role of the transducer.
