Specification of 99%/95%Al2o3 Alumina ceramic stick refractory material ceramic bar

This alumina ceramic stick comes in two grades. One is 99% pure Al2O3. The other is 95% pure Al2O3. Both grades are excellent refractory materials. They withstand very high temperatures. The 99% grade handles temperatures up to 1750°C. The 95% grade handles temperatures up to 1650°C. These sticks are incredibly hard. They resist wear extremely well. They are much harder than most metals. This hardness makes them last long in tough conditions.

Electrical insulation is another key feature. These ceramic bars are excellent electrical insulators. They work well even at high temperatures. Chemical resistance is strong too. They resist attack from many acids and alkalis. They do not corrode easily. This makes them good for harsh chemical environments. The material is also quite strong mechanically. It has good compressive strength. It handles heavy loads without breaking.

The surface finish is typically smooth. This depends on the manufacturing process. Common diameters range from 1mm to 50mm. Lengths vary widely. Standard lengths are available. Custom lengths are often possible. Tolerances are usually tight. Precision grinding achieves this. The color is generally white. It can be slightly off-white sometimes.

Manufacturing uses high-purity alumina powder. The powder gets pressed into shape. Then it gets fired at very high temperatures. This process is called sintering. Sintering makes the material dense and strong. Quality control checks are strict. Tests confirm the density. Tests confirm the hardness. Tests confirm the dimensions. Tests confirm the chemical purity. This ensures consistent performance.

Applications of 99%/95%Al2o3 Alumina ceramic stick refractory material ceramic bar

These alumina ceramic sticks are difficult. They can be found in two main grades: 99% and 95% Al2O3 purity. The high alumina web content gives them exceptional residential or commercial properties. They manage extreme warm quite possibly. This makes them perfect refractory products. Heater linings often utilize them. Kiln furnishings depends on them. They support items throughout firing without deforming.

These ceramic bars resist chemical assault. Rough acids and antacids don’t conveniently damage them. This stability is crucial in chemical processing equipment. Crucibles for melting steels use them. Thermocouple defense tubes need this toughness. Lab equipment advantages considerably.

Mechanical toughness is an additional essential function. They are extremely hard. They stand up to use remarkably well. High-wear commercial environments use them. Guides for cords utilize them. Components for grinding utilize them. They last much longer than steel components in unpleasant problems.

Thermal security is exceptional. They won’t crack under sudden temperature changes. This thermal shock resistance is critical. Fast home heating or cooling down cycles happen frequently. Semiconductor manufacturing tools uses them. Heat treatment components depend on them. Sensor real estates in hot zones require this integrity.

Electrical insulation is superb. These ceramic bars don’t carry out power. This residential or commercial property is vital in electronic devices. Protecting spacers use them. High-voltage parts utilize them. Heater elements require great seclusion. They work securely at high temperatures.

The 99% quality offers maximum performance. It has slightly far better hardness. It has a little far better temperature resistance. The 95% grade is really robust. It provides a cost-efficient remedy. Both qualities are widely utilized throughout numerous requiring markets. Metal processing uses them. Glass manufacturing utilizes them. Power generation uses them. Research laboratories utilize them. You can rely upon them for crucial high-temperature applications. Their consistency and dependability make them a top selection.

5 FAQs of 99%/95%Al2o3 Alumina ceramic stick refractory material ceramic bar

What is alumina ceramic stick? Alumina ceramic sticks are rods made from aluminum oxide. They come in high purity levels like 99% or 95%. These sticks are extremely hard. They resist wear and chemicals well. They handle very high temperatures. They are good electrical insulators.

What are the main properties? The 99% alumina sticks have higher hardness. They offer better wear resistance. The 95% alumina sticks are slightly tougher. Both types resist acids and alkalis. They maintain strength at high heat. They do not conduct electricity.

Where are these sticks used? They are common in industrial settings. Factories use them in furnace linings. They protect thermocouples in kilns. Electronics plants use them as insulators. They appear in semiconductor equipment. Welding tools use them for non-stick parts.

How should I handle them? Handle with care. These sticks are brittle. Avoid impacts or drops. Wear gloves to prevent skin cuts. Clean surfaces before installation. Use soft clamps for mounting. Never over-tighten fixtures. Tightening too much causes cracks.

What temperatures can they withstand? The 99% alumina handles up to 1700°C. The 95% alumina handles up to 1600°C. These are safe continuous use limits. Brief exposure to higher heat is possible. Avoid sudden temperature changes. Rapid cooling or heating risks breakage.
