Specifications of Excellent Electrical Insulation Alumina Ceramic Substrate Al2O3 Aluminum Oxide Plate

Alumina ceramic substrates are aluminum oxide plates. They are Al2O3. These plates provide excellent electrical insulation. This is a key reason they are widely used. High electrical resistivity is a core feature. Alumina ceramic resists electric current flow very effectively. It acts as a strong barrier against electrical conduction. This makes it safe and reliable for many electrical applications.

These substrates offer high dielectric strength. They can withstand significant voltage differences before breaking down. This property is crucial in power electronics. It prevents short circuits and component failures. The material itself is non-conductive. It does not allow electricity to pass through it easily. This inherent property ensures stable insulation performance.

Purity levels are important. Common grades are 96%, 99%, and 99.5% Al2O3. Higher purity generally means better insulation properties. It also improves other material characteristics. Good thermal conductivity is another benefit. Alumina effectively moves heat away from sensitive components. This helps manage operating temperatures. It prevents overheating issues.

The material handles high temperatures very well. It operates reliably in demanding thermal environments. Mechanical strength is also significant. Alumina ceramic substrates are hard and durable. They resist wear and physical damage. This toughness contributes to long-term reliability. Surface finish is usually smooth. This allows for precise component mounting and bonding.

Alumina ceramic substrates are used in many areas. They serve as bases for electronic circuits. They are found in power modules and LED assemblies. These plates are common in semiconductor devices. They are used for resistor cores and sensor housings. They function effectively as insulating plates in heaters. Their stability and insulation properties are essential.
