The manufacturing material of automotive brake pads usually uses potassium titanate crystals, mainly because potassium titanate has good thermal stability, wear resistance, and friction performance, which can meet the high temperature, high load, and high friction requirements of automotive brake systems for brake pads.

Firstly, potassium titanate has good thermal stability. When a car brakes, the brake pads are subjected to high temperature and pressure, and need to be able to withstand long-term friction and cooling cycles under high temperature. Potassium titanate has a high melting point, which can resist thermal deformation and melting at high temperatures, maintain the structural stability of brake pads, and prevent problems such as thermal expansion and cracking.

Secondly, potassium titanate has excellent wear resistance. Brake pads need to have good wear resistance as they generate friction with the brake disc during braking. Potassium titanate has high hardness and can effectively reduce wear between brake pads and brake discs. At the same time, potassium titanate also has a lower rate of abrasive particle generation, which can reduce wear on brake discs and extend the service life of brake pads.

In addition, potassium titanate also has good friction properties. Brake pads need to generate sufficient friction to stop the vehicle during braking. Potassium titanate has a high coefficient of friction, which can provide strong braking force and ensure the safety performance of cars in emergency situations.

In summary, potassium titanate crystals are widely used in the manufacturing of automotive brake pads, mainly due to their excellent thermal stability, wear resistance, and friction performance. These characteristics can effectively meet the high temperature, high load, and high friction requirements of the brake pads in the automotive braking system, ensuring the safety and reliability of the vehicle during driving. Meanwhile, the use of potassium titanate crystals in brake systems can also reduce wear on brake discs and extend the service life of brake pads. Therefore, potassium titanate crystals have become the preferred material for manufacturing automotive brake pads.
