5 FAQs of 99% Alumina Corundum Ceramic Boat Square Al2o3 Crucible for Furnace

Here are the top 5 FAQs for our 99% Alumina Corundum Ceramic Boat Crucibles:

What makes these crucibles special? They are made from 99% pure alumina. This high purity means less contamination. Your materials stay cleaner during high-temperature processes. It’s essential for reliable results in labs or production.

How hot can they go? These crucibles handle extreme heat well. They work fine up to 1750°C (3182°F). Going beyond this temperature risks damage. Always check your furnace’s max temperature matches the crucible’s limit.

Will they crack from sudden temperature changes? They resist thermal shock better than many ceramics. Still, avoid drastic temperature swings. Heat them up slowly. Cool them down slowly too. This practice extends their life significantly. Don’t plunge a hot crucible into cold water.

What sizes are typical? We offer many standard square boat sizes. Common internal dimensions include 10x10mm up to 200x200mm. Depths vary from 10mm to 50mm. Need something different? Ask us about custom sizes. We make those too.

How do I clean them? Clean them after each use. Use dilute acids like hydrochloric acid or nitric acid. Avoid hydrofluoric acid; it damages alumina. Rinse thoroughly with pure water. Dry completely before using again. Stuck material? Gentle mechanical scrubbing works, but be careful not to scratch deeply.
