Message InquiryProduct Description
Zircon powder is a powdered material made from zircon mineral through processes such as selection, crushing, and purification. Its chemical formula is ZrSiO₄, and it possesses a series of excellent properties including high melting point, high temperature resistance, wear resistance, corrosion resistance, and good dielectric performance.
Application fields:
1. Ceramic industry: Zircon powder is an important raw material for high-grade ceramic glazes and ceramic bodies, significantly improving the thermal shock resistance and mechanical strength of ceramic products.
2. Refractory materials: Due to the high melting point and good thermal stability of zircon, it is widely used in the production of refractory materials, such as the preparation of high-grade refractory bricks and refractory castables.
3. Casting industry: Zircon powder can be used as casting sand, especially in precision casting, where it can improve the surface quality and dimensional accuracy of castings.
4. Friction materials: Zircon powder plays an important role in the manufacturing of brake pads:
• Friction performance optimization: The addition of zircon powder can improve the friction performance of brake pads, especially the stability under high temperature conditions, helping to maintain a consistent and suitable friction coefficient.
• Wear resistance enhancement: The high hardness of zircon can improve the wear resistance and service life of brake pads when used as a filler.
• Heat resistance improvement: Zircon has extremely high heat resistance and thermal conductivity, which helps brake pads dissipate heat quickly and effectively during braking, reducing thermal fade and ensuring the continuous and stable operation of the braking system.
• Structural reinforcement: The addition of zircon powder can improve the microstructure of brake pads, enhancing their mechanical strength and compressive resistance.
Specific role of zircon powder in brake pads:
In the formulation of brake pads, the use of zircon powder is primarily aimed at enhancing the durability and braking performance of the pads under harsh conditions. It provides a stable friction coefficient, enhances wear resistance, and offers excellent thermal stability, allowing brake pads to maintain good braking performance during frequent and intense braking operations while reducing wear on the brake disc (drum), thereby extending the service life of the entire braking system. Additionally, the environmental friendliness and non-toxic side effects of zircon meet the strict material requirements for modern automotive components.
