Specifications of Alumina Ceramic Crucible Boat with Round Bottom for Tube Muffle Furnace

This alumina ceramic crucible boat works in tube and muffle furnaces. Its round bottom style fits typical furnace tubes well. This shape advertises even heat circulation around your example. You obtain constant heating results.

The boat is made from very pure alumina ceramic. This material handles severe heat quickly. It stands up to temperatures up to 1700 ° C (3092 ° F) for long periods. It handles unexpected temperature level modifications well. This toughness avoids fracturing throughout rapid heating or cooling down cycles.

Its surface is remarkably smooth. This avoids product sticking throughout experiments. Cleaning up is easy after use. The ceramic itself is chemically inert. It resists attack from the majority of acids, alkalis, and molten salts. Your examples stay unpolluted.

Criterion dimensions are offered. Usual options consist of 60mm, 80mm, 100mm, and 120mm in length. Width and height vary proportionally. Customized dimensions are feasible for specific demands. Ability relies on the dimension you select. Inspect the exact dimensions before getting.

The high alumina material guarantees reduced porosity. This lessens gas absorption or release during shooting. It preserves example pureness. The watercraft’s toughness supports different strong examples, powders, or tiny parts. It’s perfect for sintering, calcination, annealing, and ash screening.

These boats are breakable. Handle them thoroughly. Prevent effects or dropping. Use correct devices like ceramic-tipped tongs. Always pre-heat the boat slowly with your heating system. This protects against thermal shock. Store it in a completely dry area.

Applications of Alumina Ceramic Crucible Boat with Round Bottom for Tube Muffle Furnace

Alumina ceramic crucible watercrafts with round bottoms manage laborious inside tube muffle heaters. Their special form fits completely inside the heater tube. This round lower style protects against tension factors. Stress points create fractures during quick heating or cooling. These crucibles hold up against extreme temperature levels conveniently. They work well above 1500 ° C. This makes them crucial for high-heat jobs.

Researchers utilize them continuously for material synthesis. They hold powders securely throughout reactions developing brand-new substances. The round form guarantees also warmth distribution. Also heat is essential for regular outcomes. They are ideal for warmth dealing with tiny metal components or porcelains. The alumina product prevents contamination. Contamination damages experiments or production sets.

These boats are also ideal for sintering procedures. Sintering bonds powder particles together utilizing warmth. The alumina crucible holds the powder compact without reacting with it. Calcination needs high warmth also. Calcination drives off unstable compounds from materials. The inert alumina surface keeps the example pure. It does not add undesirable elements.

Chemical vapor deposition experiments commonly require these watercrafts. They hold the substratum material safely inside the hot area. The round bottom minimizes turbulence in gas circulations. Smooth gas flow is critical for uniform finishings. Thermal analysis like TGA uses these crucibles regularly. They hold the example while accurate weight changes are measured under warm.

Alumina stands up to strike from numerous acids, bases, and molten salts. This chemical inertness protects your samples. It additionally secures the crucible itself. The material provides great thermal shock resistance. It handles sudden temperature shifts far better than lots of porcelains. This toughness implies less substitutes. You conserve money with time. Their pureness makes sure no unwanted responses ruin your job.

5 FAQs of Alumina Ceramic Crucible Boat with Round Bottom for Tube Muffle Furnace

Here are 5 FAQs about Alumina Ceramic Crucible Boats with Round Bottom for Tube Muffle Furnaces:

What is this alumina ceramic boat used for? This ceramic boat holds small solid samples inside tube furnaces. It sits directly on the tube furnace floor. The round bottom fits standard tube shapes well. You use it for high temperature heating processes. Examples include calcination, sintering, or annealing materials.

What temperature can this crucible boat handle? It withstands very high heat. Its maximum continuous use temperature is 1700°C (3092°F). Short bursts up to 1750°C (3182°F) are possible. Do not exceed these limits. Overheating damages the ceramic.

How do I clean this alumina boat after use? Let the boat cool completely first. Remove any leftover material gently. Use a soft brush or compressed air. For stubborn residue, soak the boat in warm, dilute acid. Hydrochloric acid (HCl) often works. Rinse thoroughly with clean water after. Dry completely before reuse.

Why choose alumina ceramic over other materials? Alumina ceramic offers key advantages. It resists extreme heat extremely well. It handles sudden temperature changes much better than metal boats. Alumina is chemically very inert. It won’t react with most samples or gases. It lasts much longer than cheaper alternatives like quartz.

Are there special handling precautions? Yes, handle this ceramic boat carefully. Avoid dropping it or hitting it hard. Alumina is strong but brittle. Impacts can cause cracks or breaks. Always place it securely inside the furnace tube. Ensure it sits flat and stable before heating. Never heat a wet boat. Thermal shock will break it.
