5 FAQs of 99% Al2O3 Alumina Combustion Boat , Rectangle Alumina Ceramic Boats Crucible

What is an alumina combustion boat?
It’s a rectangular ceramic container made from 99% pure aluminum oxide. People use it in labs and industry. It holds samples during high-temperature processes like ashing or heat treatment. The material withstands extreme heat without melting or contaminating samples.

How hot can these boats get?
These 99% alumina boats handle very high temperatures. They work reliably up to 1650°C (about 3000°F). They manage short bursts even higher. This makes them suitable for furnace work and chemical analysis needing intense heat.

Why is 99% alumina purity important?
High purity means fewer impurities. Impurities can react with samples or release gases at high heat. This 99% purity ensures minimal contamination. Your test results stay accurate. The boat itself stays chemically stable and strong under heat stress.

Are these boats better than porcelain ones?
Yes, for high-heat jobs. Porcelain crucibles crack much easier at very high temperatures. Alumina boats resist thermal shock better. They last longer. They also handle much higher temperatures safely. Alumina is the smarter choice for demanding applications.

How should I handle and clean these boats?
Handle them carefully. Alumina is hard but brittle. Avoid dropping or banging them. Clean them after use. Use dilute acid or a suitable cleaning solution. Rinse well with water. Dry them completely before using them again. This prevents residue build-up affecting future tests.
