CAS 4485-12-5 Lithium Stearate Powder

Description of Lithium Stearate Powder：

Chemical property

The chemical properties of lithium stearate powder are similar to those of magnesium stearate, and its chemical stability is good. It is not easy to have significant chemical reactions with common acids, bases, salts, and other substances. However, under high-temperature conditions, lithium stearate powder may decompose or oxidize.

Physical property

The physical properties of lithium stearate powder include density, particle size, fluidity, etc. Its specific gravity is about 1.08; the particles are delicate and quickly dispersed. In addition, the lithium stearate powder also has good fluidity, which is easy to transport and operate during the production process.

Thermal stability

Lithium stearate powder has good thermal stability and can be used at high temperatures. Lithium stearate powder does not undergo significant decomposition or oxidation within the usual temperature range. However, prolonged high-temperature conditions may affect its performance.

Hygroscopicity

Lithium stearate powder has strong water absorption and can absorb water in the environment. Therefore, attention should be paid to moisture during storage and use to avoid affecting its performance.

Lubricity

Lithium stearate powder has excellent lubricity, which can reduce the coefficient of friction, reduce mechanical wear and conflict, and improve mechanical efficiency. This characteristic makes it widely used in lubricants, antiwear agents, and other fields.

Toxicity safety

Lithium stearate powder is a low-toxic substance with no apparent harm to the human body or the environment. However, prolonged high exposure may cause skin and respiratory irritation, so it is recommended to take appropriate protective measures during production, use, and storage.

How does Lithium Stearate get made?

Raw material preparation

Raw materials for lithium stearate include stearic acid, lithium hydroxide or lithium carbonate, and other possible additives. Stearic acid can be used as industrial or food-grade stearic acid, and lithium hydroxide or lithium carbonate are usually commercially available reagent-grade products. Other additives can also be added to improve the performance or appearance of the product as needed.

Reaction process

Stearic acid is mixed with lithium hydroxide or lithium carbonate in a particular proportion, usually by ball milling or stirring. It is necessary to control the temperature and mixing speed during the mixing process to ensure the raw materials are thoroughly mixed. Add an appropriate amount of water or other solvents to the diverse raw materials to form a uniform solution. The solution is then heated, usually in a water bath or an oil bath. During the heating process, stearic acid chemically reacts with lithium hydroxide or lithium carbonate to form a lithium stearate precipitate.

Filtration and drying

The reaction product is filtered to remove unreacted lithium hydroxide or lithium carbonate and other impurities. The cake is then dried to remove water and volatile components. Attention should be paid to controlling temperature and humidity during the drying process to prevent deterioration or caking of the product.

Grinding and packing

The dried lithium stearate powder is ground to make its particle size finer and distribution more uniform. Finally, the ground lithium stearate powder is packaged for use.
