Colloidal Silica Slurry
Grish colloidal silica slurries are produced by high purity silicon powder through advanced technology. They are widely used for nanometer scale chemical mechanical polishing in a variety of materials such as silicon wafer, chemical combination of crystals, precise optics, gemstones etc. We can provide different grain size to meet your requirements. According to the different PH value, it can be divided into acidic and alkaline type.
|Alkaline Type (pH:9.8±0.5)||SOQ-2A||SOQ-4A||SOQ-6A||SOQ-8A||SOQ-10A||SOQ-12D|
|Particle size (nm)||10~30||30~50||50~70||70~90||90~110||110~130|
| Appearance || Cream color or translucent liquid |
| Weight ||1.15±0.05|
| Composition ||Ingredients||Content（w%）|
| Impurity Content||≤50 ppb|
Remark:Customizations are available upon requests.
1. High removal rate, by using big size of silica particle, you can achieve fast finishing;
2. Different particle size could be made to your request;
3. High purity can diminish impurity on electrical products;
4. High smooth processing, SiO2 particles won't cause damage on physical devices.
Fiber optic connectors final finish.
