What is an alternative to graphite powder?

 Overview of graphite powder

Graphite powder is just one type of graphite in powder form that retains all the primary and secondary properties inherent in graphite.

Graphite is an allotrope of carbon. It is gray-black and opaque solid. It is greasy and stains the paper.

Its hardness is 1-2, and with the increase of impurities in the vertical direction, the hardness increases to 3-5. The specific gravity is 1.9-2.3. The specific surface area is concentrated in the range of 1-20m2/g. Under the condition of isolating oxygen, its melting point is above 3000 ℃, which is one of the most high temperature resistant minerals. It conducts electricity and heat.

Good chemical stability, corrosion resistance, not easy to react with acid, alkali and other reagents. Graphite burns in oxygen to generate carbon dioxide, which can be oxidized by strong oxidants such as concentrated nitric acid and potassium permanganate.

There is no pure graphite in nature, and it often contains impurities such as SiO2, Al2O3, FeO, CaO, P2O5, and CuO. These impurities often appear in the form of minerals such as quartz, pyrite, and carbonate. In addition, there are gas components such as water, asphalt, CO2, H2, CH4, and N2. Therefore, for the analysis of graphite, in addition to the determination of the fixed carbon content, the content of volatiles and ash must also be determined at the same time.

Graphite powder is an excellent dry lubricant but has been shown to corrode aluminium when moisture may be present. At this time, graphite can be replaced by molybdenum disulfide MoS2 powder.

Application of graphite powder

It is used as a mold release lubricant in the production of catalysts in the fertilizer industry.

Graphite powder has the characteristics of high temperature resistance and high lubricity, and can be used as a high temperature resistant lubricant substrate and a corrosion resistant lubricant substrate.

It can be used as powder metallurgy mold release agent, metal alloy raw material and lubricant in cable production.

It is used to make carbon film resistors, conductive dry molds and prepare conductive coatings.

Used as filler or performance improver for rubber, plastics and various composite materials to improve wear resistance, pressure resistance or electrical conductivity of materials.

Natural graphite has been used as a marking material for common pencils, zinc-carbon batteries, motor brushes and various professional applications.

A new application for nuclear grade graphite is ultra-high temperature reactors (UHTR) and next-generation nuclear power plants (NGNP).

Lithium nitride is the only stable alkali metal nitride

圖片
  Overview of Lithium Nitride  Li3N  Powder Lithium nitride is a metallic nitrogen compound with the molecular formula Li3N. It is the only stable alkali metal nitride. It is a purple or red crystalline solid, with a high melting point and a light green luster in reflected light and ruby color in transmitted light. Exposure to the air over a long period of time will eventually result in lithium carbonate. The chemistry of basic metal nitrides is extremely limited, and only lithium nitride is stable and easily prepared among binary compounds (sodium nitrite and potassium nitrite are prepared only under more extreme conditions). Lithium nitride belongs to the hexagonal crystal system. There are lithium and nitrogen layers composed of lithium and nitrogen atoms in lithium nitride crystal. The lithium atoms are arranged like carbon atoms in a graphite crystal, with nitrogen atoms at the center of a hexagon of lithium atoms. There is a lithium layer between the lithium and nitrogen layers.

  Overview of Zinc Sulfide ZnS Zinc sulfide  is a white to off-white or light yellow powder, which becomes darker when exposed to light, stable in dry air, and gradually oxidized to zinc sulfate when stored for a long time in humid air or containing water. Soluble in dilute inorganic acid, soluble in alkali, insoluble in water. Relative density 3.98 (alpha type), (d25) 4.102 (beta type). irritating. Is zinc sulfide fluorescent or phosphorescent? Zinc sulfide  is one of the most common phosphorescent materials. Phosphorescence is a special type of photoluminescence. Unlike fluorescent substances, phosphorescent materials emit absorbed energy immediately. What are the properties of zinc sulfide? Zinc sulfide  is white or slightly yellow powder. Turns into crystals when burned in H2S gas. Its α variant is a colorless hexagonal crystal with a density of 3.98g/cm3 and a melting point of 1700°C. Its beta variant is a colorless cubic crystal with a density of 4.102 g/cm3, which transforms to

  Overview of Tungsten Disulfide Tungsten disulfide  as a potential battery material is also expected to benefit from more market replenishment. Tungsten disulfide is a layered material with remarkable surface effects, electron mobility, thermochemical stability and high electron density of states. It has been widely used for lithium and sodium storage. For example, nanocomposites as conductive additives or graphene composites as battery cathode materials can exhibit higher specific capacity and discharge efficiency, making up for the deficiencies of single-component WS2 or C as anode materials. The advent of sodium batteries is expected to alleviate the current shortage of lithium resources on the rapid development of the new energy industry, and will further stimulate the application of transition metal dichalcogenides such as tungsten disulfide WS2 in the field of power storage.  Lithium-ion batteries are a key raw material for developing energy devices and realizing the vision of &
