5 FAQs of High Voltage Ceramics 95% Alumina Al2o3 Metallized Ceramic Plate in Electrical and Electronic Devices Metal Brazing

Here are 5 FAQs about High Voltage Ceramics 95% Alumina Al2O3 Metallized Ceramic Plates for metal brazing in electrical and electronic devices:

Why use alumina ceramics for high voltage? Alumina ceramics are electrical insulators. They stop current flow effectively. This is vital for high voltage safety. They also handle intense heat well. This matches brazing process temperatures.

How does the metallization work? A special paste coats the ceramic surface. This paste contains metals like molybdenum and manganese. The assembly gets fired in a kiln. The heat bonds the metal layer permanently to the ceramic. This creates a strong, conductive surface ready for brazing.

Why braze metal to this ceramic? Brazing joins metal parts securely to the metallized layer. It forms a hermetic seal. This seal prevents leaks. It also creates a reliable electrical connection. Brazed assemblies withstand vibration and thermal cycling.

Why choose 95% alumina specifically? 95% alumina offers the best balance. It provides excellent electrical insulation. It has high mechanical strength. Its thermal conductivity is good. Its thermal expansion matches many metals. This reduces stress at the joint. Higher purity levels cost more without significant gain for most brazing uses.

Where are these brazed plates used? They are common in demanding electrical parts. You find them in power semiconductor packages. They are used in high voltage feedthroughs and bushings. They serve in vacuum interrupters. They work in X-ray tube components and laser housings. These applications need strong insulation, vacuum integrity, and heat tolerance.
