JC004 polishing slurry of silicon crystal material Chemical Co., Ltd. in Shenzhen produce a new generation of water-soluble high-purity colloidal slurry, widely used in silicon wafer polishing process. In the practical application of these products with superior performance particle size, high concentration, high purity, low metal ion contamination customer has been fully affirmed. The main features of JC004 polishing slurry-type silicon material using specially selected nanoscale SiO2 hydrosol as an abrasive. Minimal contamination with metallic impurities, easy to clean, polish, high speed, damage layer is small, flatness and so on. In the polishing can be optimized according to need different proportions, can achieve the best results. Compared with similar products in the United States and Japan, these products have a high concentration of small abrasive particle size, surface tension, for organics, metal ions and particles are easy to clean, polish rate is high (0.8 ~ 1.5μm / min), high temperature Non-homogenized pits, etc. does not appear. The main purpose is mainly used for high-quality multi-diffusion wafer polishing, polishing process can also be used raw germanium, quartz, silica, sapphire and other materials, but also for the diffusion sheet polishing. The basic parameters of the test items index Appearance visual detection method milky white liquid Solid content by weight (%) France 40 ± 2 pH value (20 ℃) ??pH meter 11.5-12.5 particle size (nm) laser particle size analyzer 80 ± 10 Density (20 ℃, g / mL) using the method recommended densitometer 1.27-1.30 JC004 slurry and deionized water ratio of 1:10, the ratio can also be changed according to the actual requirements of the process. Transport and Storage 1. Transport and storage temperature is 5 ℃ ~ 50 ℃, should be stored away from light, in order to avoid deterioration of the slurry. 2. The shelf life of one year, six months within the recommended use. 3. Avoid metals, particulate pollution, avoid contact with strong electrolyte Packing: 25kg / barrel.
