High Purity Nickel Ni powder CAS 7440-02-0, 99%
Description of Nickel powder ：
Nickel powder is silver-white and has a metallic luster. Depending on the specific preparation process, its shape can be spherical, cube, diamond, etc.. The particle size of the nickel powder can be adjusted according to the application requirements. Generally, the finer the particle size, the larger the specific surface area, and the better the physical and chemical properties of nickel powder. The density of nickel powder is about 7.8g/cm3. Porosity refers to the percentage of porosity in the total volume of nickel powder, affecting the hygroscopicity, electrical conductivity, and plasticity. Nickel powder has high stability to air, water, alkali, and other substances at room temperature. It is not easily oxidized or chemically reactive with these substances. Nickel has good corrosion resistance and is not easily affected by the atmosphere and certain chemicals. It is resistant to sulfuric acid., nitric acid, hydrochloric acid, and other acids. Nickel powder is magnetic and can be attracted by magnets. This characteristic makes the nickel powder have special uses in special applications, such as magnetic recording, electromagnetic shielding, etc. In catalyst preparation, nickel powder is often used as a catalyst carrier or active component, showing good catalytic activity.
Application of Nickel powder ：
Nickel powder is a very important raw material in battery manufacturing. It makes positive electrode materials for batteries, such as nickel-cadmium and nickel-metal hydride batteries. Nickel powder has high energy density, good electrochemical performance, and durability, which can improve the energy density and life of the battery.
Nickel powder is a common catalyst carrier used to prepare a range of catalysts. These catalysts are commonly used in oil cracking, ammonia synthesis, hydrogen production, and other industrial production. Nickel powder as a catalyst carrier can provide high surface area and good mass transfer performance, thus improving catalyst activity and selectivity.
Nickel powder is an important alloying element in superalloys, which can improve alloys' strength, corrosion resistance, and high-temperature stability. Nickel powder can also be used to prepare certain single-crystal superalloys, which have excellent high-temperature properties and can be used in high-temperature applications such as aircraft engines and rockets.
Nickel powder is commonly used as a colorant and filler in cosmetics. It can provide cosmetic products with beautiful color and texture while enhancing cosmetics' moisturizing and nourishing effects.
Nickel powder has magnetic properties and can be used to prepare magnetic materials. These magnetic materials can manufacture magnetic storage devices such as tapes, disks, recorders, electromagnetic shielding, heating, and other applications.
Nickel powder can be used to prepare wear-resistant coatings with high hardness and good wear resistance and can manufacture wear-resistant parts and structural parts.
Nickel powder can be used for the preparation of cermet materials. Cermet is a new type of material that combines the advantages of metal and ceramic materials and has high strength, hardness, wear resistance, and high-temperature resistance. As one of the raw materials of cermet, nickel powder can improve the material's mechanical properties and wear resistance.
Production Method of Nickel powder ：
The physical method uses mechanical grinding and other physical means to prepare nickel blocks or alloys into nickel powder. The method mainly includes ball milling, crushing, grinding, etc.
The ball milling method is to put the nickel block or nickel alloy into the ball mill, add the right amount of the grinding medium (such as zirconia, alumina, etc.), and grind at a certain speed for a certain time so that the nickel block or nickel alloy is broken into fine particles.
The crushing method is to put the nickel block or nickel alloy into the crusher, add an appropriate amount of grinding media (such as diatomaceous earth, glass beads, etc.), and crush at a certain speed for a certain time so that the nickel block or nickel alloy is broken into fine particles.
The grinding method is to put the nickel block or nickel alloy into the grinder, add an appropriate amount of grinding agent (such as alumina, silicon carbide, etc.), and grind at a certain speed for a certain time so that the nickel block or nickel alloy is ground into fine particles.
The chemical method is the method of converting nickel raw material into nickel powder by chemical reaction. Common chemical methods include electrolysis, hydrogen reduction, and gas deposition.
Electrolysis is the electrolysis of an aqueous solution containing nickel ions in an electrolytic cell, which causes nickel ions to discharge on the cathode and form nickel powder. The advantages of this method are high production efficiency, environmental pollution, and high production cost.
Hydrogen reduction uses hydrogen to reduce nickel oxides or nickel-containing raw materials under high temperatures and pressure to produce nickel powder. The advantages of this method include lower production costs and less pollution to the environment, but safety needs to be paid attention to in the production process.
The vapor deposition method is to heat the compound gas containing nickel at high temperatures in the reactor to condense the nickel atoms onto the cold substrate to form nickel powder. The advantages of this method are that the nickel powder produced has high purity and fine particle size, but the production cost is high.
To sum up, Different production methods come with different advantages and drawbacks. The choice of the best method of production relies on the particular requirements of the application as well as the manufacturing environment.
