Products introduction
In electric vehicles, high-power packaging devices play a key role in controlling vehicle speed and in storing and converting alternating current and direct current. Yet high-frequency thermal cycles put strict requirements on the heat dissipation of electronic packaging. At the same time, the complexity and diversity of the working environment require packaging materials of Metallized Ceramic Components to have good thermal shock resistance and high strength to play a supporting role.
Currently, the main ceramic substrates that have been mass-produced and widely used include Al₂O₃, BeO, SiC, Si₃N₄, AlN, etc. Among them, silicon nitride is widely recognised at home and abroad as the best Metallized Ceramics material with overall performance such as high thermal conductivity and high reliability. But overall, in terms of properties like thermal conductivity, wear resistance, and mechanical properties, both Si₃N₄ and AlN ceramic substrates have become substrate materials worthy of attention in the future.
Ceramic Relays
Electronic control technology is an important sign to measure the development level of new energy-saving electric vehicles. High-voltage DC Ceramic Metallization relays are the core components of electronic control systems. High-voltage DC vacuum relays have vacuum chambers sealed with metal and ceramics. Ceramic to Metal insulators are slidably connected between moving contact components and push rods. This keeps the moving and static contacts in good electrical insulation with the magnetic circuit system formed by parts such as the relay's magnetic yoke plates and iron cores, whether they are on or off. This ensures the relay's arc-breaking ability when switching high-voltage DC loads. Arcs are the main cause of vehicle spontaneous combustion. Only relay products with "arc-free" switching can fundamentally solve the problem of "spontaneous combustion".
Products technology
Now, as the automotive industry continues to develop and people's requirements for vehicles in terms of environmental protection, energy efficiency, safety, and comfort keep rising, automotive materials are also constantly changing. Especially in the wave of electrification, the system design of cars has undergone earth-shaking changes. Advanced Ceramic Metallization materials are slowly emerging in the application of new energy vehicle parts.
Advanced Metalized Ceramic materials are composed of ionic or covalent bonds. So they have excellent properties such as high strength, high hardness, high temperature resistance, wear resistance, corrosion resistance, and good biocompatibility. But because most ceramic powders are ionic or covalent compounds, traditional sintering processes for making dense Metallization Ceramic materials require higher sintering temperatures and longer holding times. This inevitably leads to grain coarsening and residual pores, which in turn affect the performance of ceramic materials.
To solve such problems, sintering is the most important link. Currently, how to achieve rapid densification of materials at lower sintering temperatures, and to produce ceramic blocks that are completely pore-free, have uniform structure, fine grains, and strengthened grain boundaries, remains a constant goal pursued by Metallized Ceramics material scientists. The innovation of ceramic sintering equipment and technology is the most critical factor to further improve the performance of advanced ceramic materials.
our Products
In this context, our Ceramic Metallizations stand out as a key solution. These components combine the excellent properties of advanced ceramics with the conductivity of metals, making them highly suitable for the demanding environments of new energy vehicles. They can be applied in high-voltage electronic packaging, where their high thermal conductivity-derived from premium ceramic substrates like Si₃N₄ and AlN-ensures efficient heat dissipation during high-frequency thermal cycles. Their strong mechanical strength and resistance to thermal shock also make them ideal for supporting and protecting core electronic parts in complex working conditions.
Moreover, our Metallized Ceramic Components are produced using advanced sintering technologies that address the issues of traditional processes. They achieve high densification at relatively lower temperatures, resulting in fine and uniform grains with minimal pores. This not only preserves the inherent advantages of ceramics but also ensures consistent performance, making them a reliable choice for various critical parts in new energy vehicles. As the automotive industry continues to advance towards electrification, our Metallization Ceramics are poised to play an increasingly important role in enhancing the efficiency, safety, and durability of new energy vehicles.
