ADDITION TO MODIFIED ABRASIVE SUSPENSIONS BASED ON AІ203, TECHNOLOGY FOR ITS PREPARATION
Recommended application field:
The addition to the abrasive slurry for polishing stage of monocrystalline silicon wafers for enterprises of electronic and optical industries.
Advantages over analogues:
Development and production high modifitsuruyuschey additives allow unsubscribe from imported materials and reduce the cost per unit of final product. Adding a builder in the abrasive slurry increases sedimentation and aggregative stability of the system and saves it for a long period of time. Using the additives will increase the speed and quality of polishing wafers of semiconductor materials.
Description of the development: () The highly builder to abrasive slurry for polishing stage of monocrystalline silicon wafers. Non-toxic.
- Work flow additive per 10 liters. slurry - 100 ml;
- Yield ratio - 92.1%;
