The nickel niobate market has great development potential and the preparation process continues to improve.

Nickel niobate, with the chemical formula NiNb2O6, can be used as anode materials, thermal barrier coating materials, microwave dielectric ceramic materials, etc. It is used in the manufacturing of lithium-ion batteries, aerospace engines, communication equipment, radar, etc., and has great market development potential.

Lithium-ion batteries can be used in 3C electronics, electric vehicles, energy storage and other fields. Energy density, charge and discharge speed, and cycle life are important performance parameters of lithium-ion batteries. High charge and discharge rates will affect battery energy density and reduce battery cycle life. At present, lithium-ion batteries are the mainstream secondary battery products, but their performance cannot meet the needs of all application fields and they are constantly being improved and upgraded.

According to the “In-depth Market Research and Investment Strategy Suggestions Report on Nickel Niobate Industry 2023-2027” released by the Industrial Research Center, niobium Nickel acid is used as anode material. Compared with traditional anode material graphite, the energy density is higher, and it can still be restored to the original energy storage level after multiple rapid charges, with little impact on cycle life. Scientists from the University of Twente in the Netherlands have developed a lithium-ion battery using nickel niobate as the negative electrode material, which can charge 10 times faster than current lithium-ion batteries. This shows that nickel niobate anode material has huge development potential in the field of lithium-ion batteries, especially in the electric vehicle industry.

Aero engines and automobile engines have high operating temperatures. This is mainly because high combustion temperatures can improve fuel utilization and provide more powerful power. In particular, aero engines have extremely high operating temperatures. In order to protect parts, thermal barriers will be covered on the surface. coating. Nickel niobate ceramic has the advantages of high melting point, low thermal conductivity, and strong high-temperature stability. It can be used as a thermal barrier coating material for aeroengines. However, its strength and hardness need to be further improved, and can be improved by optimizing the sintering process.

Microwave dielectric ceramics are used as dielectric materials in microwave band circuits. They have functions such as resonance and filtering, and are indispensable in the communications industry. Nickel niobate ceramics have excellent electromagnetic properties. Nanocrystalline single-phase nickel niobate ceramic blocks can be used as microwave dielectric ceramic materials, but they also need to optimize the sintering process to improve product strength, hardness, density and other properties.

Industry analysts said that traditional nickel niobate preparation processes mainly include solid phase method, hydrothermal method, etc., but the comprehensive performance of the product is limited , the application is restricted. Using niobium compounds and nickel compounds as raw materials, after mixing, add inorganic salts and ethanol for wet mixing, dry and grind them into powder. After heating, washing, drying and other processes, nickel niobate powder can be obtained, which can be used as anode material.

Using nickel niobate powder prepared by traditional technology as raw material, mixed with metal oxide powder, placed in a mold and using discharge plasma sintering method to prepare high-strength and high-hardness ceramics, which can be used as thermal barrier coatings. Using nickel niobate powder prepared by traditional technology as raw material, adding sintering aids, mixing evenly, and sintering under a certain pressure, the obtained ceramics have improved mechanical properties, density, etc., and can be used as microwave dielectric ceramics.
