Specifications of Al2O3 Alumina Combustion Boat with Lid , Rectangle Alumina Ceramic Boats Crucible

These alumina ceramic boats are made for high-temperature work. They’re crafted from pure 99.6% Alumina Oxide (Al2O3). This material handles extreme heat well. The standard size is 80mm long, 15mm wide, and 12mm high. The matching lid fits snugly on top. This lid helps contain samples and gases during heating.

These boats resist temperatures up to 1650°C (3002°F). They also handle rapid temperature changes very well. This thermal shock resistance is crucial. It prevents cracking when heating or cooling quickly. Their dense structure gives them good chemical stability. They resist attack from many acids and bases. This makes them suitable for various sample types.

You’ll find these boats are strong mechanically. They resist wear and abrasion effectively. Their smooth surface makes sample loading and cleaning easy. Crucially, they show minimal contamination. This purity is vital for sensitive analytical work.

These rectangular boats are essential tools in many labs. They work perfectly for sample preparation in analytical chemistry. They’re ideal for ashing materials to measure organic content. They’re used in thermogravimetric analysis (TGA) to track weight changes under heat. They serve well for sintering small ceramic or metal parts. They’re also used for calcination processes requiring high purity.

The included lid is important. It helps prevent sample loss during volatile reactions. It minimizes contamination from furnace atmospheres. It ensures more consistent results. These boats offer reliable performance for demanding high-heat applications.

5 FAQs of Al2O3 Alumina Combustion Boat with Lid , Rectangle Alumina Ceramic Boats Crucible

What is an Alumina Combustion Boat?
It’s a rectangular container made from alumina ceramic. Alumina is aluminum oxide (Al2O3). The boat holds samples during high-temperature processes. It comes with a matching lid. The lid covers the sample inside.

Why use alumina ceramic?
Alumina ceramic handles extreme heat very well. It withstands temperatures over 1700°C. This material resists chemical attack. It doesn’t react with most substances. It provides excellent thermal stability. Samples stay secure during intense heating.

What temperatures can it handle?
This alumina boat tolerates continuous use up to 1700°C. Short bursts can reach 1800°C. Check the specific product rating. Never exceed the maximum temperature. High purity alumina offers the best performance.

Why is a lid important?
The lid prevents sample loss. It stops material from spilling out. It protects the sample from direct flame exposure. The lid reduces contamination risks. It helps contain gases or fumes. The lid ensures more consistent heating conditions.

Where is this boat used?
Scientists use it in laboratories. Common applications include sample combustion. It’s used in ash content determination. It works for heat treatment processes. It’s suitable for sintering and calcination. It serves well in materials research. It supports catalyst studies. It’s ideal for high-temperature reactions.

How should I handle it?
Handle the alumina boat carefully. It is a brittle ceramic. Avoid impacts or drops. Use clean tools. Thermal shock can crack it. Heat and cool it gradually. Follow recommended heating rates. Store it in a safe place. Keep it away from hard surfaces.
