Hexagonal Structure Alumina Ceramics Sheet Wear Resistance Smooth Surface

Product introduction

Al2O3 ceramics: high alumina content, relatively dense structure, with special properties, so it is called special ceramics. Al2O3. The ceramic material is a close-packed hexagonal structure composed of oxygen ions, and aluminum ions filled in two-thirds of the octahedral gap. This is the same stable α-Al2O3 structure as natural corundum, so ceramics have a high melting point high Hardness, and excellent wear resistance. The hardness of the ceramic patch is ≥HRA85, second only to the hardness of diamond, and the surface is smooth and the friction coefficient is small, and the wear resistance is very ideal, especially in the high-temperature oxidizing medium or corrosive medium, the ceramic patch material has better performance than other metal materials. Much superior.

Product Features

1. High hardness: The Rockwell hardness of the alumina ceramic sheet is above HRA85, which is second only to diamond and exceeds the wear resistance of wear-resistant steel and stainless steel. To

2. Excellent wear resistance: its wear resistance is equivalent to 30 times that of manganese steel and 20 times that of high chromium cast iron.

3. Lightweight: its density is about 3.6g/cm³, which is only half that of steel, which can greatly reduce the equipment load. To

4. Corrosion resistance: good resistance to sulfuric acid, hydrochloric acid, nitric acid, strong alkalis, salt, etc.

5. Convenient construction: Alumina ceramic sheets are suitable for large-area construction

6. ZTA ceramic sheet: The service life can reach more than 5 times that of alumina wear-resistant ceramics. Zirconia wear-resistant liners have higher fracture toughness, high bending strength, and high wear resistance, and are used in high-end anti-wear fields.

7. Process: Using dry pressing and isostatic pressing, high temperature firing, Rockwell hardness HR85, wear resistance, and impact resistance, can effectively extend the service life of various equipment and wearing parts.
