5 FAQs of 22.3—99.7% Alumina Al2O3 Ceramic Solid Rods

What are the alumina purity grades available?
We offer rods from 22.3% to 99.7% Al2O3. The 22.3% grade is more cost-effective. Higher purity grades like 85%, 95%, 99.5%, and 99.7% perform better technically. Choose based on your specific needs and budget.

How much heat can these rods handle?
Heat resistance depends on the alumina content. Standard grades (like 85% or 95%) handle temperatures up to 1600°C. The top 99.7% grade withstands even higher temperatures, around 1750°C. Check the exact specs for your chosen grade.

Can you machine these rods to custom sizes?
Yes. We supply rods in standard diameters and lengths. We also offer precision machining. We cut rods to your exact requirements. We can grind diameters or create special shapes. Tell us what you need.

Are the rods resistant to chemicals?
Yes. Alumina ceramic rods resist most acids and alkalis very well. They handle harsh chemicals much better than metals or plastics. This makes them good for chemical processing equipment, pumps, and lab tools. They won’t rust or corrode easily.

Do they conduct electricity?
No. Alumina ceramic is an excellent electrical insulator. Even at very high temperatures, it blocks electricity well. This property is vital for electrical insulators, furnace parts, and sensor housings where electrical isolation is critical.
