Overview of advanced ceramics in the automotive industry
The automotive and transportation landscape is changing rapidly. From autonomous driving technologies to electric and advanced fuel systems to car sharing and connected mobility, the transportation systems of the future will require new and innovative technologies, materials and designs. Systems will run hotter, run longer, and have more electrical and wireless connectivity. At the same time, conventional vehicles with internal combustion engines continue to dominate, and the performance standards for these systems continue to rise.
In electric drive systems, high-performance ceramics are used as electrical insulating materials to protect components such as power electronics or sensors from high temperatures and electric arcs. Due to its high wear resistance and hardness, it is used in braking systems and bearings to extend service life and reduce maintenance requirements. It is also used in batteries, where ceramics are used as diaphragms to improve the safety and efficiency of lithium-ion batteries. All in all, the lightweight properties of technical ceramics also help to reduce the total weight of vehicles, which is particularly beneficial for the range of electric vehicles!

ceramic battery components and insulation assemblies increase safety and service life thanks to their excellent resistance to high temperatures and chemical stability. In electric motors and charge controllers, wear-resistant rolling bearings and insulation components optimize efficiency and operational reliability even under high loads.
Battery Modules
High-temperature resistant and chemically inert ceramics provide cell-to-cell, module-to-module and pack-level protection. The high dielectric strength of alumina and aluminum nitride means they are all-purpose electrical insulators. This is crucial for components in electric powertrain battery modules, where electrical isolation is essential.
In addition, the high thermal conductivity of these technical ceramics helps the battery module dissipate heat efficiently. Technical ceramics can also be combined with heat-absorbing materials to enhance heat absorption.
Electric Vehicle Motor Shaft Bearings
To prevent arcing in electric vehicle traction motors, silicon nitride bearing balls provide the ideal combination of mechanical strength and resistivity. Unlike steel, silicon nitride hybrid bearing assemblies provide strong electrical insulation without compromising critical mechanical properties. Silicon nitride bearing balls are extremely smooth, low friction and tough enough to withstand shock loads, and are extremely hard and durable for high rolling efficiency.
