Specifications of 99% Alumina Ceramic Square Corundum Boat

This 99% Alumina Porcelain Square Diamond Boat deals with severe heat and rough problems. It is made from really pure alumina powder. This product is sintered at extremely high temperatures. The outcome is a dense, difficult ceramic part. The watercraft form is square. It has level sides and a flat base. This style works well for holding samples during high-temperature processes.

The alumina material is high, a minimum of 99%. This high purity gives the boat outstanding properties. It stands up to extremely heats, as much as 1650 ° C continuously. It can handle brief ruptureds also hotter, approximately 1750 ° C. The boat does not melt or flaw quickly at these temperature levels. It also withstands chemical strike. Acids and antacids generally don’t harm it. It is not affected by many liquified metals or salts. This makes it appropriate for lots of requiring lab and industrial usages.

The watercraft is very strong mechanically. It has high solidity. It is also extremely tight. The ceramic material does not conduct power. This is very important for some applications. The boat takes care of unexpected temperature level modifications well. It doesn’t crack conveniently when heated up or cooled rapidly. This thermal shock resistance is a key advantage. The product wears slowly. It stands up to abrasion gradually. The surface area is really smooth. This helps avoid sample contamination. The shade is normally a grayish white.

Requirement sizes are offered. Typical dimensions include length, width, and height. Regular sizes could be 50mm long, 20mm large, and 15mm high. Various other dimensions are possible. Personalized sizes can frequently be made. The boat is dimensionally stable. It maintains its shape and size even after duplicated heating cycles. Its flat surfaces guarantee stable sample positioning. This alumina watercraft supplies trusted efficiency. It is a resilient selection for demanding furnace job. It endures problems that damage many other products.

Applications of 99% Alumina Ceramic Square Corundum Boat

99% alumina ceramic square corundum boats take care of extremely high warmth well. They stand up to chemical strikes successfully. These homes make them essential sought after commercial work. Semiconductor making relies on them heavily. They carry silicon wafers securely with heating system actions like oxidation or diffusion. The boats preserve pureness. They protect against contamination of sensitive wafers. Product warm treatment makes use of these boats too. They hold parts throughout annealing or sintering processes. The watercrafts withstand the extreme heat needed. They maintain their shape reliably. Research laboratory screening take advantage of alumina boats. Researchers utilize them for calcining powders or firing samples. The inert nature of alumina avoids reactions. Results stay exact. Managing fragile products ends up being easier. The square form offers security. Filling and discharging examples is simple. Thermal shock resistance is an additional key point. These watercrafts endure fast home heating and cooling cycles. This prevents splitting during manufacturing. Lengthy life span minimizes replacement prices considerably. Chemical handling plants utilize the boats. They transfer stimulants or various other materials needing high temperatures. Alumina’s resistance protects the contents. Electronic devices element production employs these watercrafts. They support parts during firing or glazing steps. Precision is maintained. The smooth surface area minimizes sticking. Cleaning is simple after usage. Durability under harsh problems defines these alumina boats. They offer a reputable solution for vital high-temperature movement.

5 FAQs of 99% Alumina Ceramic Square Corundum Boat

What’s the highest temperature this ceramic boat can handle?
It withstands temperatures up to 1700°C continuously. This makes it perfect for high-heat processes like tube furnace work. It stays stable without cracking.

How well does it resist chemicals?
Its 99% alumina content gives strong chemical resistance. It works well with most acids and molten salts. Avoid strong alkalis like hot caustic soda. They can slowly damage it.

Why pick 99% alumina over cheaper types?
Higher purity means better performance. It lasts longer under extreme heat and chemical stress. Lower purity ceramics wear out faster. You get more value over time.

What sizes are usually available?
Standard sizes fit common tube furnaces. Typical boats might be 50mm, 80mm, or 100mm wide. Lengths vary too. Custom sizes are possible for specific needs.

How should I clean it after use?
Use mild methods. Soak it in warm, dilute acid or an ultrasonic cleaner. Avoid harsh scrubbing. Never use abrasive cleaners. They scratch the surface.
