Boron Nitride products are synthesized from boric acid and melamine at high temperature. Boron Nitride has the advantages of less impurities, high purity, good crystallinity, and adjustable particle size. For different industries, Boron Nitride is mainly divided into: boron nitride for ceramics, Boron Nitride for thermal conductivity, Boron Nitride for cosmetics and Boron Nitride for lubrication. Boron Nitride is used as polymer additives such as functional plastics, epoxy resins, silica gels, polyimides, polyurethanes, nylons, etc. The main function of Boron Nitride is to enhance thermal conductivity, insulation, friction resistance, corrosion resistance, and reduce dielectric constant and dielectric loss.
The Boron Nitride is divided into two specifications according to different grades, BNR-01 and BNR-02.The chemical composition of the product should meet the requirements in the following table (mass fraction).

1. Appearance of Boron Nitride:
The boron nitride product should be a uniform white powder. There are no visible inclusions in the product.
2. Physical and chemical properties of Boron Nitride:
Theoretical density: 2.27. Mohs hardness: 2
3. Uses of Boron Nitride: additives for advanced lubricating greases, release agents for optical glass products, additives for lubricating coatings. 4. Chemical composition of Boron Nitride: The Boron Nitride is divided into two specifications according to different grades, BNR-01 and BNR-02.The chemical composition of the product should meet the requirements in the following table (mass fraction). Specifications purity（wt.%） B2O3（wt.%） particle size D50（um） Tap density（g/cm3） specific surface area（m2/g） BNR-01 ≥99 ≤0.2 3-25 0.3-0.5 5-30 BNR-02 ≥98.5 ≤0.8 3-25 0.3-0.6 2-18 5. Packaging of Boron Nitride: Product packaging is divided into barrels. The inner packaging is sealed with double-layer plastic bags, and the outer packaging is made of fiberboard drums with a net weight of 20kg. After packaging, they are sealed with lead seals.

On January 30, 2023, molybdenum price rose by more than 20% in a single day, breaking a new 17-year high. Molybdenum is known as the "war metal", "steel warrior". Molybdenum is valued by more and more countries. China is the world's richest country in molybdenum resources, with reserves of 4.3 million tons, followed by the United States (2.7 million tons) and Chile (1.8 million tons), which acco...more
