5 FAQs of 95% Alumina Ceramic Wafer Good Insulating Al2O3 Disc Aluminum Oxide Ceramic Substrate

Here are five common questions about 95% Alumina Ceramic Wafers:

What is this 95% Alumina Ceramic Wafer?
This is a thin, flat disc made mostly from aluminum oxide (Al2O3). The “95%” means it’s 95% pure alumina. We make it by pressing fine alumina powder and firing it at very high heat. The result is a hard, smooth disc used mainly as a base or insulator in electronics and other technical fields.

Why is the alumina ceramic good for insulation?
Alumina ceramic doesn’t conduct electricity. It stops electrical current very effectively. This makes it a top choice for insulating parts. It keeps electricity safely where it belongs. It prevents short circuits. Its high electrical resistance is a key reason people use it.

How well does it handle heat?
This ceramic handles high temperatures extremely well. It doesn’t melt or break down easily under heat. It can work reliably in environments up to about 1600°C. It also moves heat away efficiently. This heat spreading ability protects sensitive components nearby. Things stay cooler and work better.

What sizes and shapes are available?
These wafers come in many standard sizes. Common diameters range from small (like 10mm) to larger sizes (over 100mm). Thicknesses are usually thin, like 0.5mm, 1.0mm, or 2.0mm. We can also make custom sizes and shapes. We cut or machine the ceramic precisely to meet specific project needs.

Where do people use these alumina ceramic discs?
Their main use is as a base for electronic circuits. They hold things like resistors and microchips securely. You find them in power electronics, LED lights, sensors, and heaters. They insulate heating elements. They protect parts in high-voltage equipment. They also serve in lasers and other demanding applications needing a tough, insulating base.
