Application of aluminum nitride in new energy vehicles

Utilizing an AlN ceramic substratum as the provider of the chip can separate the chip from the component heat dissipation base plate. The AlN ceramic layer in the middle of the substratum can successfully boost the insulation capacity of the component (ceramic layer insulation holds up against voltage > 2.5 KV). The aluminum nitride ceramic substrate has excellent thermal conductivity. The thermal conductivity can reach 170-260W/ m · K. These superb residential properties make light weight aluminum nitride copper-clad laminate the first choice for high-voltage IGBT component product packaging. Additionally, the expansion coefficient of the AlN ceramic substrate is similar to that of silicon, which will certainly not create stress damage to the chip. The peeling-off resistance of the AlN ceramic substrate is > 20N/mm2. It has exceptional mechanical buildings and rust resistance and is not vulnerable to deformation. It can be utilized in a large range of applications. Usage within the temperature variety enhances the integrity of high-voltage IGBT components.

The key to high-performance aluminum nitride ceramics lies in powder preparation.

Aluminum nitride powder preparation technology can be divided into direct nitridation method, carbothermal reduction method, self-propagation method, plasma method, chemical vapor phase method, solution method, and high-energy ball milling method.

Common methods for preparing aluminum nitride powder

Among them, the carbothermal reduction method ranks first, accounting for nearly 50%, followed by the direct nitriding method and the self-propagation method, accounting for 26% and 12%, respectively. These three methods are also methods that have achieved industrial application. The technology of these methods is relatively mature, the equipment requirements are relatively simple, and the purity of the output products is also high. However, these processes involve complex formulas and steps, high production energy consumption, and certain safety risks. These factors have restricted the development of aluminum nitride in large-scale commercial applications.

The global sintered brake pad market size is expected to reach US$1,138.5 million in 2029

According to the latest report, "Global Sintered Brake Pads Market Report 2023-2029," by the QYResearch research team, the global sintered brake pads market is expected to reach US$1,138.5 million in 2029, with a compound annual growth rate of 7.0% in the next few years.


Sintered brake pads, overall global market size

The chart/data above is extracted from QYResearch's latest report, "Global Sintered Brake Pads Market Research Report 2023-2029.

Main drivers:

Enhanced Performance and Durability: Sintered brake pads are famous for their superior performance and durability compared to traditional organic brake pads. Drivers often prefer sintered brake pads because they can withstand high temperatures, provide consistent braking performance, and exhibit longer service life in demanding conditions.

High Heat Resistance: One of the main advantages of sintered brake pads is their excellent heat resistance. This property makes them particularly suitable for high-performance vehicles and demanding applications, such as heavy-duty trucks and sports cars, where the braking system experiences high temperatures during operation.

Improved stopping power: Sintered brake pads enhance stopping power, making them the first choice for drivers focused on safety and responsiveness. The ability to achieve strong and reliable braking, especially in extreme conditions, has contributed to the popularity of sintered brake pads.

Extended service life in demanding conditions: Vehicles operating in challenging environments such as off-road conditions or heavy-duty applications benefit from the extended service life of sintered brake pads. This durability factor is a significant driver for the adoption of sintered brake pads across various industries.


Main obstacles:

Cost Considerations: Sintered brake pads typically have higher manufacturing costs than organic or semi-metallic alternatives. This higher cost can be a significant limitation, especially in price-sensitive markets or for consumers looking for a more economical brake pad option. The high price of sintered brake pads may limit their adoption among budget-conscious car owners.

Noise and Vibration: Sintered brake pads may produce more noise and vibration during braking than organic alternatives. This could be a problem for consumers who prioritize a quiet, smooth braking experience. Noise issues can affect overall driving comfort and may lead some consumers to choose quieter brake pad options.

Brake disc wear: Sintered brake pads, while durable, are abrasive and may increase disc wear. The potential for accelerated rotor wear may result in more frequent rotor replacements, thereby increasing maintenance costs. This consideration may lead some consumers to choose brake pads that contribute less to rotor wear.

Dust Generation: Sintered brake pads produce more brake dust than other types. Dust may contain metal particles that can accumulate on the wheels and affect the vehicle's appearance. Consumers who prioritize clean and low-maintenance braking systems may consider this a drawback.

Limited Cold Weather Effectiveness: Sintered brake pads may exhibit reduced effectiveness in extremely cold weather conditions. In the event of a significant temperature drop, the braking performance of sintered brake pads may be affected until optimal operating temperature is reached. This limitation can be a problem in areas with harsh winter weather.
