5 FAQs of Manufacturing Dry Pressing Moulding 99% Al2O3 Alumina Ceramic Block Plate

What is the alumina content in these ceramic blocks? The alumina content is 99%. This high percentage makes the blocks extremely hard and durable. They resist wear and corrosion better than lower-grade ceramics. This makes them suitable for harsh environments like heavy machinery or high-temperature setups.

What applications are these blocks used for? They are commonly used in industrial settings. Examples include wear-resistant linings, electrical insulators, and high-temperature furnace parts. Their strength and thermal stability make them ideal for machinery components exposed to stress or heat. They also work in chemical processing equipment due to their corrosion resistance.

How does dry pressing moulding improve quality? Dry pressing uses high pressure to compact ceramic powder into precise shapes. This method reduces air pockets and uneven density. The result is a uniform, dense product with consistent performance. It also allows tight control over dimensions, minimizing the need for post-production machining.

Can these blocks handle extreme temperatures? Yes. They withstand temperatures up to 1600°C. Their low thermal expansion prevents cracking under rapid temperature changes. This makes them reliable for applications like kiln furniture or thermal barriers. They maintain structural integrity even during prolonged heat exposure.

Are custom sizes and shapes available? Yes. Manufacturers offer customization based on technical drawings or samples. Production molds can be adjusted to create specific dimensions or surface textures. Lead times vary depending on design complexity.
