Special Diamond Micron Powder
Introduction:
Special type Diamond powder is the use of high-quality single Crystal Diamond Diamond CSD series of raw materials, precision production and processing technology, crushing, shaping, purification, special acid treatment, grading and other processes processed.Mainly used in the production of PCD tool with composite sheet, PDC field with composite sheet, Diamond wafer, Diamond die core, TSP and Diamond wire saws.
Product introduction:
| CSDM-PCD/PDC Features: high strength, high purity CSD series Diamond as raw material, using precision production and processing technology, crushing, shaping, special purification, special acid-base treatment, grading and other processing, products pale yellow, crystal shape rules, uniform particle size distribution concentration, impurity content control in parts per million (less than 5PPM), good thermal stability, high wear resistance.Micronized surface after special treatment process, the particle surface is smooth and clean, more conducive to the composite sheet, stable growth of polycrystalline. Use: suitable for the production of PCD tool composite sheet, PDC oilfield coalfield composite sheet and cobalt-based CD wire drawing die core. |
| CSDM –TSP Features: high quality CSD series Diamond as raw material, using precision production and processing technology, crushing, shaping, purification, special acid treatment, grading and other processes processed, products pale yellow, crystal shape rules, uniform particle size distribution concentration, impurities very low, good thermal stability, high wear resistance. Uses: suitable for the production of PDC stone composite sheet, TSP and silicon polycrystalline wire drawing die core. |
| CSDM -WS Features: high strength CSD series of diamond as raw material, the use of advanced production and processing technology, the crushing, shaping, purification, grading and other processes processed products pale yellow, crystalline rules, was close to the equal volume oval-shaped particles, particle size concentration and uniformity, low impurity content, wear resistance, good dispersion. Uses: suitable for the production of diamond wire saw or other diamond cutting tools for cutting Sapphire, polycrystalline silicon, Monocrystalline silicon, precious stones, quartz plates, LED display, liquid crystal glass, magnetic materials, Semiconductors and other valuable and fragile high-tech materials. |
