Specification of 99.7 Polished Alumina Oxide Alumina Al2o3 Ceramic Rod for Crystal Growth

This alumina ceramic pole is made from 99.7% pure light weight aluminum oxide (Al2O3). Its high purity is crucial for requiring applications. The product supplies superb efficiency. It holds up against extremely high temperatures well. It manages sudden temperature level adjustments well. It withstands attack from strong chemicals successfully. It shows high electrical insulation properties. It possesses excellent mechanical hardness.

The pole is precisely brightened. This develops an exceptionally smooth surface area coating. A smooth surface is vital for crystal development procedures. It reduces nucleation sites where unwanted crystals could begin. It allows for better control over crystal formation. It aids create higher quality crystals with less flaws. The rod’s geometry corresponds along its size. This makes certain consistent heating and development conditions.

Key requirements define its efficiency. The alumina pureness is assured at 99.7% minimum. This reduces contamination risks for sensitive crystals. Its thickness is high, commonly going beyond 3.90 g/cm ³. High thickness suggests far better mechanical strength. It likewise suggests far better resistance to put on and erosion. The product has a really reduced porosity. Low porosity stops gas trapping. It protects against liquid penetration. This preserves process integrity.

Its thermal properties are strong. It has low thermal expansion. This stability stops splitting under warm cycles. Its high thermal conductivity assists disperse warmth uniformly. Consistent home heating is critical for regular crystal development. The rod displays exceptional dielectric toughness. This is vital for processes including high voltages.

This ceramic pole is created for integrity. It supplies a steady, inert platform. It sustains the severe problems of crystal development heaters. Its polished surface and high purity directly contribute to effective crystal production end results. Appropriate handling is advised to protect the surface area finish.

Applications of 99.7 Polished Alumina Oxide Alumina Al2o3 Ceramic Rod for Crystal Growth

These ultra-smooth 99.7% alumina ceramic poles are important tools in crystal growth. Their vital advantage is the refined surface area coating. This refined coating reduces physical contact factors with the crystal. Much less contact means much less opportunity for damage or unwanted nucleation. Preventing issues is vital for high-quality crystal yield.

The product itself, Al2O3, is extremely steady at high temperatures. Crystal development procedures frequently need severe warmth. These alumina poles deal with these temperatures without softening or buckling. Consistent dimensional stability is crucial for accurate crystal positioning. Maintaining position over long growth cycles makes sure consistent crystal structure.

Alumina is chemically inert. It withstands attack from extreme chemicals and reactive environments. This inertness avoids contamination of the melt or vapor. Contamination damages crystal purity. Keeping the development environment tidy is non-negotiable for high-purity crystals like sapphire or silicon carbide.

The poles provide a secure, non-reactive placing surface. They hold seed crystals firmly during growth. The high purity alumina makes sure no contaminations leach right into the delicate crystal material. Pollutants cause issues and decrease crystal performance. This purity level is essential for demanding applications.

You see these rods used in Kyropoulos and Czochralski methods. They are common for expanding huge sapphire crystals. Sapphire is used for LED substratums and optical home windows. They are also employed for silicon carbide and various other innovative semiconductor materials. The rods sustain the seed crystal throughout the entire drawing or cooling down procedure.

Various other materials usually fall short. Steels can introduce contaminants or thaw. Less pure porcelains could lose particles. Reduced thickness alumina might not hold up against thermal biking. These refined 99.7% Al2O3 rods address these problems. They use the integrity needed for regular, high-volume crystal production. This dependability converts directly right into better returns and reduced costs.

5 FAQs of 99.7 Polished Alumina Oxide Alumina Al2o3 Ceramic Rod for Crystal Growth

What makes 99.7% purity important?
High purity alumina is critical. It prevents harmful stuff from getting into your crystal melt. Your crystals grow cleaner and better this way. Impurities ruin crystal quality.

Why is thermal shock resistance good?
These rods handle quick temperature changes very well. They won’t crack easily going from hot to cold. This is vital during crystal growth cycles. Temperature shifts happen a lot.

What sizes are available?
Standard diameters are common. Think 3mm, 5mm, 8mm, 10mm. Lengths usually go up to 500mm or more. We make custom sizes too. Just ask for what you need.

How smooth is the surface?
The surface finish is very smooth. It’s precision polished. This minimizes contact points with your crystal. Your crystal grows freely without sticking.

How should I handle these rods?
Handle them carefully. Wear clean gloves. Fingerprints or dirt can cause problems later. Don’t drop them or hit them hard. They are strong but can chip.
