Specification of High Temperature High Purity 99% 99.7% Al2O3 Flat Plate Alumina Ceramic bar Aluminum Oxide Strip

These alumina ceramic bars and strips are flat plates made from aluminum oxide (Al2O3). They are designed for demanding high-temperature applications. You get two purity levels: 99% and 99.7% Al2O3. The higher purity (99.7%) offers slightly better performance. Both grades are extremely strong and durable. They resist wear exceptionally well.

These components handle very high heat. They work reliably in environments exceeding 1500°C. Their thermal stability prevents cracking or warping under intense heat. This makes them perfect for furnace parts, kiln furniture, and heat treatment fixtures. They provide excellent electrical insulation even at extreme temperatures. This property is vital for electronic applications.

The material is very hard. It resists scratches and abrasion effectively. This hardness ensures a long service life in harsh conditions. Chemical resistance is another key feature. Alumina ceramics withstand attack from many acids and alkalis. They are suitable for corrosive settings.

Standard dimensions are available. Common thicknesses range from 1mm to 20mm. Widths often go up to 200mm. Lengths can reach 300mm or more. Custom sizes are usually possible. Surface finishes are precise. Options include as-fired, ground, or polished surfaces. This depends on your application’s tolerance needs.

These alumina plates are essential in many industries. Semiconductor manufacturing uses them for wafer processing parts. Metallurgy relies on them for furnace linings and thermocouple tubes. Laboratory equipment incorporates them for high-heat components. Laser systems utilize them for stable platforms. They are also found in wear-resistant guides and liners.

Applications of High Temperature High Purity 99% 99.7% Al2O3 Flat Plate Alumina Ceramic bar Aluminum Oxide Strip

This product is flat plate alumina ceramic bars and strips. They are made from aluminum oxide, known as Al2O3. The purity levels are high: 99% and 99.7%. These ceramics handle extreme heat well. They work in environments above 1500°C. Their strength remains stable at these temperatures. They resist thermal shock too. Sudden temperature changes won’t crack them easily.

These bars and strips are very hard. They outlast metals in abrasive conditions. They don’t wear down quickly. Their surface stays smooth. This reduces friction in moving parts. They resist chemical attack also. Acids and alkalis don’t damage them. This makes them safe for harsh industrial settings.

Electrical insulation is another key feature. They block high voltages effectively. This is vital in electronics. They serve as substrates for circuits. They insulate components in power devices. Heat sinks use them for thermal management. Semiconductor tools rely on their stability. They hold silicon wafers during high-heat processes.

Furnace builders use these ceramics. They line kilns and reactors. They form shelves and supports inside. Their heat tolerance prevents warping. They keep furnace operations efficient. Laser systems incorporate them too. They guide beams without absorbing energy. Their reflectivity stays consistent.

Medical equipment benefits from alumina’s purity. It doesn’t react with body tissues. It’s safe for surgical tools. Dental components use it. Prosthetics and implants employ these ceramics. Their biocompatibility meets strict standards.

Industrial machines install them as wear plates. They protect against erosion. Conveyor systems use them as guides. They cut down maintenance costs. They replace metal parts that fail faster. Their longevity saves money over time.

These ceramics fit custom designs. Manufacturers cut them to precise sizes. They polish edges for safety. They drill holes for assembly needs. Custom shapes are possible. This flexibility suits many technical uses.

5 FAQs of High Temperature High Purity 99% 99.7% Al2O3 Flat Plate Alumina Ceramic bar Aluminum Oxide Strip

Here are 5 common questions about our High Temperature High Purity Alumina Ceramic Bars (99%/99.7% Al2O3 Aluminum Oxide Flat Plate Strips):

What purity levels do these alumina bars offer?
We supply two primary purity grades. The standard grade is 99% Al2O3. We offer a higher grade at 99.7% Al2O3. The higher purity minimizes impurities. This improves performance in critical applications. Both grades guarantee exceptional chemical resistance.

How much heat can these ceramic bars handle?
These bars resist very high temperatures. They operate reliably long-term up to 1650°C (3000°F). They handle short bursts even hotter. This makes them perfect for furnace parts, kiln furniture, and thermal processing equipment. They won’t soften or deform under normal high-heat use.

What sizes and shapes are available?
We focus on flat plate strips and rectangular bars. Common thicknesses range from 1mm to 25mm. Widths often go from 10mm to 200mm. Lengths can be up to 500mm or more. Custom sizes are possible. Tell us your specific dimensions.

Are different surface finishes an option?
Yes. The standard finish is a smooth, fine-ground surface. We offer rougher finishes like as-fired for certain uses. We also provide precision polishing for applications needing an ultra-smooth surface. The finish choice depends on your function, like sealing or wear resistance.

Where are these alumina bars typically used?
Their main strengths are heat resistance, electrical insulation, and wear resistance. You find them in furnace linings, semiconductor processing tools, high-temperature sensors, electrical insulators, and wear plates. They are ideal where metals or plastics fail due to heat or corrosion. They handle harsh chemical environments well.
