Hafnium Diboride HfB2 Powder CAS 12007-23-7, 99%

Description of Hafnium Diboride HfB2 Powder :

Hafnium diboride is an inorganic compound with a high melting point, high density, good electrical conductivity, and corrosion resistance, and its molecular formula is HfB2. Hafnium diboride is a gray to black crystal, usually in powder or block form. Its crystal structure is hexagonal, similar to the crystal structure of aluminum diboride. Hafnium diboride has a high density and hardness, good thermal conductivity, and chemical stability. Hafnium diboride is insoluble in water and acids at room temperature and does not react with water and acids. It can react with certain metals and alloys at high temperatures, such as iron, nickel, cobalt, and other metals, to produce alloys with higher melting points. In addition, hafnium diboride also has good oxidation resistance and can resist oxidation and corrosion at high temperatures.

Application of Hafnium Diboride HfB2 Powder :

(1) High-temperature material field: 

Hafnium diboride has a high melting point and hardness, which can be used as a high-temperature material. With the continuous development of the field of high-temperature materials, the demand for hafnium diboride will continue to increase. For example, it can manufacture high-temperature crucibles, high-temperature furnaces, and test equipment. In addition, hafnium diboride can also be used as a high-temperature lubricant and high-temperature coating material.

(2) Field of wear-resistant materials: 

Hafnium diboride has good corrosion resistance and high hardness and can be used as a wear-resistant material. With the continuous development of the field of wear-resistant materials, the demand for hafnium diboride will continue to increase; for example, it can be used to manufacture brake pads for high-speed railways, automotive brake pads wear-resistant bearings and other wear-resistant parts 

(3) Synthesis of other brides: 

Hafnium diboride is an important raw material for the synthesis of other borides. Borides with different compositions and functions can be prepared by reacting with different types of borates. For example, nitrides can be prepared by reacting with non-metallic elements, and carbides and silicides can be prepared by reacting with metal elements, such as intermetallic compounds. 

Production Method of Hafnium Diboride HfB2 Powder :

Preparation of raw materials: Boric acid (H3BO3) and sodium hydroxide (NaOH) are the main raw materials, and deionized water is also required as a solvent. 

Preparation of boric acid solution: Dissolve boric acid in deionized water to form boric acid solution. 

Preparation of sodium hydroxide solution: Dissolve sodium hydroxide in deionized water to form sodium hydroxide solution. 

Mixing boric acid solution and sodium hydroxide solution: The boric acid solution and sodium hydroxide solution are mixed to obtain a mixed solution. 

Adjust pH value: Use ammonia or other alkaline substances to adjust the pH value of the mixed solution to 8 ~ 9. 

Add stabilizer: Add an appropriate amount of polyethylene glycol to the mixed solution after adjusting the pH value as a stabilizer to slow down the precipitation rate of hele diboride. 

Crystallization: The mixed solution is placed in the crystallizer, the control temperature is between 0 ~ 10℃, crystallization of hele diboride. 

Separation and washing: hele diboride from the solution by centrifugal separation or filtration, and then hele diboride with deionized water to remove the residual mother liquor. 

Drying: Put the washed hele diboride into the dryer, dry to constant weight, and get dry hele diboride product. 

Packaging: the dry hele diboride for metering packaging to get the final product. 

The above is a production method of hele diboride; different manufacturers or regions may be adjusted or optimized according to the specific needs and actual conditions. In addition, the various operations involved, such as dissolution, pH adjustment, crystallization, separation, washing, and drying, must be carried out under appropriate conditions to ensure product quality and yield.

Prospect Market of Hafnium Diboride HfB2 Powder :

Hafnium diboride is a compound with important uses, mainly used in glass, ceramics, enamel, and other industries; boron additives can also be used as a catalyst, additives, dyes, and so on. With the development of the economy and the continuous progress of technology, the application field of hele diboride continues to expand, so its market demand is also growing. 

From the perspective of the glass industry, Hafnium diboride is an important additive for glass network formation and structure modification. Adding hele diboride can improve the hardness of glass, chemical stability, optical properties, etc., improve the quality of glass products, and add value. At the same time, with the continuous development of automobiles, construction, electronics, and other industries, the demand for glass products is also increasing, and the market demand for hele diboride is also increasing correspondingly. 

Hafnium diboride also has a wide range of applications in the ceramic and enamel industry. Adding Hafnium diboride can improve the strength, wear resistance, corrosion resistance, and other properties of ceramic and enamel products. Still, it also can improve the product's thermal stability and shock resistance. Therefore, with the continuous development of construction, homes, electronics, and other industries, the demand for ceramics and enamelers is also increasing. 

In addition to the application in the traditional field, Hafnium diboride has a broad application prospect in the new field. For example, Hafnium diboride can be used as a new catalyst and additive for organic synthesis, environmental protection, and other fields. In addition, Hafnium diboride can also be used as a dye intermediate for dye production. The application prospects of these new fields also bring good opportunities to the Hafnium diboride market. 

In addition, from the policy level, the state has given a certain support and encouragement policy for the boron chemical industry, which is conducive to further developing the Hafnium diboride industry. With the deepening of the national supply-side structural reform and the continuous improvement of green development, higher requirements are also put forward for the boron chemical industry. Enterprises need to continuously improve the ability of independent innovation, develop new products, processes, technologies, and services, and improve the added value of products and market competitiveness.
