Global boron nitride powder market trend 2024-2028 What is Boron Nitride Used For? by Newshelencastor

Recently, on Sinopec's annual results teleconference, the company representative answered questions about the oil prices, and said that the future trend of oil prices is still very uncertain, and it is expected to be around $100 this year and $85 next year respectively.

Sinopec, "There are many factors affecting oil prices at the moment, including geopolitics, macroeconomic trends, the implementation of the policy of OPEC+, the strength of the US DOLLAR and so on. We see a lot of uncertainty in the future oil prices. It is impossible to predict the accurate price, but a general trend could be estimated."

According to Sinopec, international institutions generally have a forecast of around $100 this year and around $85 next year in the oil prices. As geopolitical problems and other issues ease next year, oil prices will be lower than this year.

The volatile oil prices in the international market will continue to affect lots of industries and the supply of many boron nitride powder.

Cubic boron nitride (CBN) is a super-hard material synthesized by hexagonal boron nitride and catalyst at high temperature and high pressure. Among the super-hard materials which have been industrially applied, the hardness of CBN is second only to diamond. The thermal stability of cubic boron nitride is much higher than that of diamond, and it has greater chemical stability to iron series metal elements, so cubic boron nitride abrasives are widely used in the field of cutting and grinding of iron-based metal products.
 

Types of Cubic Boron Nitride CBN
There are two kinds of cubic boron nitride: single crystal and polycrystalline sintered body.
The single crystal is prepared by hexagonal boron nitride and catalyst at a pressure of 3000 ~ 8000 MPA and a temperature of 800 to 1900. Typical catalyst materials are selected from alkali metals, alkaline earth metals, tin, lead, antimony and their nitrides. The crystal forms of cubic boron nitride include tetrahedral truncated cone, octahedron, crooked crystal and double crystal. Industrial cubic boron nitride is available in black, amber and metal-plated surfaces, and the particle size is usually less than 1 mm.
 

Application of Boron Nitride Polycrystals in Metal Cutting
Cubic boron nitride polycrystal (PCBN) tool is a kind of super-hard material product which is composed of many fine grains (0.1μm 100μm) CBN.
 
It not only has high hardness and high wear resistance, but also has the characteristics of high toughness, chemical inertia, red hardness and so on, and can be sharpened by diamond grinding wheel. It shows excellent cutting performance in all aspects of cutting, and can achieve stable cutting at high temperature. it is especially suitable for machining all kinds of hardened steel, tool steel, chilled cast iron and other high hardness difficult-to-machining materials. The tool has the advantages of sharp cutting, good shape retention, high wear resistance, small unit wear, less correction times, and is conducive to automatic machining. it is suitable for all cutting processes from roughing to finishing.
 

Performance and Properties of PCBN
PCBN not only has most of the properties of CBN, but also overcomes the shortcomings of directional cleavage of CBN single crystal plane, and has many performance advantages.
 
1. High hardness. The hardness of PCBN tool is second only to diamond and much higher than that of cemented carbide and ceramic tools, so it can process hardened steel, cast iron and cemented carbide with hardness above HRC60.
 
2. High wear resistance. The wear resistance of PCBN tools is much higher than that of cemented carbide and ceramics, and its service life is usually 3 to 5 times longer than that of ceramic tools and 5 times to 15 times that of cemented carbide tools.
 
3. High chemical inertia. The chemical reaction between PCBN and iron group elements and their alloys is not easy to occur at 1200 to 1300, which overcomes the chemical affinity between polycrystalline diamond tools and iron, has high oxidation resistance, and the bonding and diffusion effect on various materials is much less than that of cemented carbide.
 
4. High thermal stability. The heat resistance of PCBN can reach 1400, which is much higher than that of diamond tools (700 to 800). It is proved that the cutting temperature above 1100 can still maintain high sharp cutting performance, which is suitable for dry cutting.
 
5. High thermal conductivity. Among all kinds of tool materials, the thermal conductivity of PCBN is 79.54W/(m·k), which is second only to diamond and much better than cemented carbide, and the thermal conductivity of PCBN will be improved with the increase of temperature.
 
6. Low friction coefficient. Compared with other tool materials, the friction coefficient of PCBN is low. The friction coefficient between PCBN and different materials is about 0.1 ~ 0.3, while that of cemented carbide is 0.4 ~ 0.6, and the friction coefficient decreases with the increase of cutting speed, so that the cutting force decreases and the phenomenon of chip sticking is reduced.
 

Application of Cubic Boron Nitride in Grinding Field
Cubic boron nitride grinding tools have excellent grinding performance, which can complete the processing of difficult-to-grind materials, improve productivity and effectively improve the grinding quality of workpieces. It can also strictly control the shape and size of the workpiece and improve the surface integrity of the workpiece after grinding, so as to improve the fatigue strength of the parts and prolong the service life.
 
Cubic boron nitride micro-powder is suitable for resin, metal, ceramic and other binder systems, can also be used in the production of polycrystalline composite sheets, can also be used as loose abrasives, grinding paste and so on.

Affected by the present complex international situation and the epidemic, the future of global financial markets, futures markets, and stock markets is still highly uncertain. For this reason, I suppose the price of the boron nitride powder would continue to rise.
