製品の説明
Polishing Powder for Sapphire Substrate
Description
Cerium oxide is primarily known as the "gold standard" for polishing glass and softer crystals. While it is rarely used alone as a primary abrasive for sapphire due to sapphire's extreme hardness (9 on the Mohs scale), specialized cerium-based formulations are used for specific final finishing stages in precision sapphire optics.
Role of Cerium Oxide in Sapphire Polishing
Final Finishing/Superpolishing: High-purity cerium oxide nanoparticlesare used to achieve ultra-low surface roughness.
Chemical-Mechanical Polishing (CMP): cerium oxide is one of several critical abrasives used in CMP slurries for sapphire. It facilitates a synergistic chemical reaction that smooths surfaces beyond what simple mechanical grinding can achieve.
Composite Blends: Manufacturers often blend cerium oxide with harder minerals like alumina to bridge the gap between high material removal and mirror-like finishes.

Q&A
1. What is cerium oxide polishing powder?
Cerium oxide polishing powder is a high-purity compound widely used for polishing optical components, semiconductor wafers, and other delicate surfaces like glass and lenses. Its fine particles and exceptional chemical properties make it ideal for achieving high levels of clarity and smoothness without damaging the surface being polished.
2. How do I choose the right cerium oxide polishing powder for my application?
Selecting the right polishing powder depends on the material you are polishing and the desired finish. Factors such as particle size, purity, and the specific requirements of your polishing process should guide your choice. Our sales team can assist you in choosing the optimal product for your needs.
3. How should I store cerium oxide polishing powder?
Store cerium oxide polishing powder in a cool, dry place, away from direct sunlight and moisture. Keep it in sealed, airtight containers to prevent contamination. Proper storage ensures the product maintains its quality and effectiveness over time. When stored correctly, cerium oxide polishing powder typically has a shelf life of 1-2 years.
4. Do you provide customized cerium oxide formulations?
Yes, we offer customized cerium oxide polishing powders and slurries tailored to meet specific performance requirements. Whether you need adjustments to particle size, chemical composition, or slurry consistency, we can create a formulation that best suits your needs.
5. Can I get a sample before making a bulk order?
Yes, we provide samples of our cerium oxide polishing powder and slurry for evaluation. Please contact us to request a sample, and our team will arrange the shipment.
6. How can I place an order? What is the typical delivery time for cerium oxide products?
You can place an order by contacting our sales team. We will guide you through the process, help with product selection, and provide you with a quote based on your needs. We’ll provide an estimated delivery schedule once the order is confirmed. Delivery times depend on the order size, location, and whether the product is in stock.
