5 FAQs of Tabular Alumina Aluminium Oxide Plate Shaped Corundum Fine Powder for Electronic Ceramic Semiconductor Device Block Welding

What is tabular alumina?
It’s pure aluminum oxide powder. It gets heated until crystals form flat plates. These plate shapes are important. They make the powder pack tightly together. This powder is super stable when hot.

Why use it for electronic ceramics?
Electronic parts get very hot during welding. Tabular alumina handles this heat. It doesn’t crack or change shape much. It blocks electricity well. This keeps signals clean in devices. It’s also very strong.

What size powder works best?
You need fine powder. Small particles melt evenly. They fill gaps completely. This makes a solid ceramic block. Big particles leave holes. Holes are bad. They weaken the block. Fine powder gives a smooth finish.

How pure must it be?
Extremely pure. Even tiny impurities cause problems. They can mess up the ceramic. They can ruin the semiconductor device. Good tabular alumina has over 99.5% Al2O3. Low soda levels are critical. This prevents defects.

Why is sintering important?
Sintering fuses the powder particles. It makes the ceramic strong. Tabular alumina sinters well. Its plate shapes lock together tightly. This creates a dense, tough material. It won’t break under stress. This is vital for reliable devices.
