Sulfide powder refers to the chemical compounds powder with large families of inorganic and organic compounds, e.g. copper sulfide, Zinc sulfide, molybdenum disulfide, tungsten disulfide powders and so on. Sulfides and their similar compounds include a series of metals and semi-metallic elements combined with S, Se, Te, As, Sb, Bi minerals. Applications of Sulfide powder Sulfide powders are widely used in industrial field. Molybdenum disulfide is a catalyst in organic synthesis. Since sulfur-containing organic compounds such as thiophene poison the common hydrogenation catalyst, molybdenum disulfide can be used to catalyze the hydrogenation reaction of sulfur-containing organic substances. Cadmium sulfide can be used to make photo-voltaic cells. Lead sulfide is used to make infrared sensors. Zinc sulfide and cadmium sulfide are used to make phosphors, and high purity cadmium sulfide is a good semiconductor. Tetraphosphorus trisulfide is used to make matches and fireworks. Tetraphosphorus tetrasulfide is used in the manufacture of insecticides, lubricating oil additives and flotation agents. Sodium sulfide is widely used in the manufacture of sulphur dyes, production of organic drugs and pulp, etc. Calcium sulphide and strontium sulfide are used to make luminescent lacquers. 3pdm provide high purity molybdenum sulfide, tungsten disulfide, cadmium sulfide,bismuth sulfide,stannic sulfide,zinc sulfide, etc. Payment Term: T/T, Western Union, Paypal, Credit Card etc. Shipment Term: By air, by sea, by express, as customers request. Storage conditions: 1) Store in a dry environment at room temperature. 2) Avoid damp and high temperature. 3) Use immediately after opening the inner packing bag.

What is Colloidal Gold

What is Colloidal Gold ? Colloidal Gold refers to a sol- or colloidal suspension made of gold nanoparticles in water. The most common colloids are wine red for spherical particle sizes less than 100nm and blue/purple for larger spherical particle sizes or nanorods. The optical, electronic, molecular recognition and molecular recognition properties of gold nanoparticles […]

What are gold nanoparticles used for?

What exactly is colloidal or sol gold? It is a colloidal suspension (or colloidal solution) of nanoparticles of gold in fluid (usually water). Colloid colors are typically wine red for spherical particle sizes less than 100nm or blue/purple (for more spherical particles, or nanorods). Property of Colloidal Gold Colloid gold nanoparticles’ properties and applications are […]

What is Colloidal Silicon Dioxide?

What exactly is colloidal silica dioxide? A gaseous silica obtained by hydrolysis. It’s a form of fine silicon, which is easily dispersed. It can be insoluble in water. It’s a common element on the periodic table. It’s non-toxic, and it is used often in industry. It is the second most abundant element in the crust […]

What is Nano Silver Good For?

Why is nano-silver good for you? The benefits of using nano-silver in various industries such as pharmaceuticals, healthcare, and consumer goods. These nanoparticles can be very tiny particles, with sizes from 1 to 100 nanometers. Nanosilver is composed of Silver nanoparticles. These nanoparticles are useful as antibacterial or antifungal agents in the industry, water treatment, […]
