Specifications of 95% 99% Alumina Sagger Crucible Ceramic Boat with Lid

These alumina sagger crucible boats are tough, reliable containers. They are made from high-purity alumina ceramic. You get two main purity options: 95% alumina and 99% alumina. The 99% version is harder and withstands higher temperatures. Both resist extreme heat very well. They handle temperatures up to 1700°C easily. This makes them perfect for demanding furnace work.

These ceramic boats are built for long life. They resist chemical attack. Acids and bases won’t damage them easily. They also handle sudden temperature changes well. You won’t see cracks from quick heating or cooling. This durability saves money over time. You replace them less often.

The design is simple and functional. Each ceramic boat comes with a matching lid. The lid fits securely. This lid protects samples inside the furnace. It keeps contamination out. It also helps control the furnace atmosphere. You can choose different sizes. Common sizes are 50mm, 80mm, and 100mm long. Width and height vary to match. The walls are thick enough for strength. They stay stable during repeated thermal cycling.

These crucible boats are essential for high-temperature processing. They work in labs. They work in factories. They hold materials securely during sintering, annealing, and calcination. Samples stay safe inside. The alumina material keeps the process clean. It prevents unwanted reactions. It provides consistent results batch after batch. You need dependable equipment for critical heat treatments. These sagger boats deliver that dependability. They are a fundamental tool for materials work.

Applications of 95% 99% Alumina Sagger Crucible Ceramic Boat with Lid

Alumina sagger crucible ceramic boats with lids are essential tools for high temperature work. These containers handle extreme heat reliably. The 95% and 99% alumina grades offer distinct advantages.

The 95% alumina crucibles work well up to about 1600°C. This grade is cost-effective for many common processes. It provides good chemical resistance. It withstands thermal shock adequately for routine furnace cycles. These boats are widely used for sintering metal powder compacts. They protect parts during firing. They are common in ceramic component manufacturing. They hold parts securely during high heat treatment. The lids prevent contamination and minimize heat loss.

The 99% alumina crucibles perform at even higher temperatures, exceeding 1700°C. This ultra-high purity is critical. It minimizes any risk of contamination for sensitive materials. The surface is exceptionally smooth. This prevents sticking, especially for advanced ceramics or thin films. This grade is necessary for demanding semiconductor applications. It ensures pure crystal growth environments. It is vital for annealing high-performance alloys requiring absolute purity. The lid is crucial here too. It seals the environment inside the boat tightly. It protects valuable samples from furnace atmosphere effects.

Both types offer excellent dimensional stability. They maintain their shape cycle after cycle. This reliability is key for consistent production results. The ceramic material resists attack from many fluxes and chemicals. This durability extends their usable life. Choosing between 95% and 99% alumina depends on the process temperature needed. It also depends on the purity requirements of the material being processed. These crucible boats provide a stable, inert platform for critical high-temperature steps. They are fundamental in labs and factories needing precise thermal processing. The fitted lid adds significant protection and control.

5 FAQs of 95% 99% Alumina Sagger Crucible Ceramic Boat with Lid

95% & 99% Alumina Sagger Crucible Ceramic Boat with Lid FAQs

What’s the main difference between 95% and 99% alumina?
The number tells you the purity. 99% alumina has more pure ceramic material. This makes it stronger. It handles higher temperatures better. It resists chemicals better. It lasts longer under tough conditions. 95% alumina is good for many jobs. 99% alumina is better for extreme heat and harsh chemicals.

How hot can these crucibles get?
These crucibles handle very high heat. 95% alumina works up to about 1600°C. 99% alumina handles up to 1800°C. Always check the exact specs for your model. Never exceed the maximum temperature rating. Going too hot damages the crucible.

How long do they last?
Lifespan varies a lot. It depends on the alumina purity you choose. It depends on the temperatures you use. It depends on the materials you process inside. It depends on how carefully you handle them. Expect several uses. 99% alumina usually lasts longer than 95% alumina under the same conditions. Avoid sudden temperature changes. Avoid physical bumps. This extends their life.

Why is a lid important?
The lid does several key jobs. It keeps the material inside the boat contained. It prevents dust or other stuff from falling in. It helps control the atmosphere around your sample. It reduces heat loss. It protects your material. Always use the matching lid designed for your specific crucible boat.

How do I clean them after use?
Cleaning is usually simple. Let the crucible cool down completely first. Never put a hot crucible in water. Thermal shock cracks it. Use water or mild solvents. Use soft brushes or tools. Avoid anything gritty or abrasive. Scratching the surface hurts performance. For stubborn residues, consult the manufacturer. Follow their recommended cleaning procedure.
