9 Mohs Wear-Resistant Zirconia Craft Bead for Grinding Zirconia Beads
Product Introduction
Zirconia craft beads are a high-performance ceramic material made of zirconia powder sintered at high temperature. Commonly used in granules or grinding media, with high hardness, high density, high wear resistance, high corrosion resistance, high temperature stability and other advantages, suitable for abrasives, abrasives, chemical, electronics, medical and other industrial fields. The size and shape of zirconia process beads also adapt to different applications. As a high-end wear-resistant material, it has a very wide range of application prospects.
Feature
1. High hardness: Compared with other abrasives, zirconia craft beads have higher hardness and are able to grind and disperse the target substance more effectively.
2. Strong corrosion resistance: zirconia process beads will not be corroded by acids, alkalis, salts and other chemicals, and can remain stable in different environments.
3. High temperature resistance: zirconia craft beads can withstand high-temperature baking, high-temperature calcination and other treatments, and will not cause sintering deformation or rupture due to high temperature.
4. Uniform particle size: Zirconia process beads have advanced production technology and high preparation accuracy, so the particle size distribution is uniform, which helps to improve product quality.
5. Ultrafine powder: The size of zirconia craft beads can be prepared to submicron level, and this high-purity zirconia micropowder can be used to prepare advanced materials.

Application
1. Catalyst: Because zirconia has high chemical and thermal stability, zirconia craft beads are often used as reusable immobilization catalyst carriers.
2. Grinding and polishing: zirconia process beads have high hardness, wear resistance, high temperature resistance and corrosion resistance, so they can be used as efficient abrasives for roughing, finishing and superfinishing of various materials.
3. Spraying: Zirconia process beads have excellent wear resistance, heat resistance and chemical stability at high temperatures, so they can be used as spraying materials in automobile manufacturing, aerospace, energy and other fields.
Preparation technology
1. Material preparation: Grinding and screening zirconia raw materials to obtain zirconia powder with uniform particle size.
2. Ingredients: Add the required additives to zirconia powder, mix evenly to prepare ingredients.
3. Wet molding: the ingredients are added to the water and stirred into a paste, and then the process beads are made by extrusion molding or rolling molding.
4. Drying and calcining: After drying the formed process beads in a low temperature oven, sintering is carried out in a high temperature calcining furnace to make its crystal structure more dense and improve hardness and wear resistance.
5. Surface treatment: polishing and surface treatment of calcined craft beads to make their surface smoothness and roundness higher.
