JCB JSDM Series specialized diamond micropowder is made from high-quality single crystal diamond JSD series of JCB as raw material. It is processed through precise manufacturing techniques, including crushing, shaping, purification, special acid-base treatment, and grading. JCB specialized diamond micropowder is mainly used for the production of PCD cutting tool composites, PDC oilfield and coalfield composites, diamond polycrystalline sheets, diamond polycrystalline wire drawing die cores, TSP, diamond wire saws, and so on.
JSDM -PCD/PDC Features: Made from high-strength, high-purity JSD series diamond raw materials, processed through precision manufacturing techniques, including crushing, shaping, special purification, special acid-base treatment, and grading. The product is light yellow, with regular crystal shape, uniform and concentrated particle size distribution, impurity content controlled at a few parts per million (less than 5PPM), good thermal stability, and high wear resistance. The micro-powder surface is treated with a special process, making the particle surface smooth and clean, more conducive to the stable growth of composite sheets and polycrystalline diamonds. Applications: Suitable for producing PCD cutting tool composite sheets, PDC composite sheets for oil and coal fields, cobalt-based CD wire drawing die cores, etc. | |
JSDM –TSP Features: Made from high-quality JSD series diamond raw materials, processed through precision manufacturing techniques, including crushing, shaping, purification, special acid-base treatment, and grading. The product is light yellow, with regular crystal shape, uniform and concentrated particle size distribution, extremely low impurity content, good thermal stability, and high wear resistance. Applications: Suitable for producing PDC stone composite sheets, TSP, and silicon-based polycrystalline wire drawing die cores, etc. | |
JSDM -WS Features: Made from high-strength JSD series diamond raw materials, processed through advanced manufacturing techniques, including crushing, shaping, purification, and grading. The product is light yellow, with regular crystal shape, nearly equiaxed elliptical particles, concentrated and uniform particle size, extremely low impurity content, strong wear resistance, and good dispersibility. Applications: Suitable for producing diamond wire saws or other diamond cutting tools, used for cutting sapphire, polysilicon, single crystal silicon, gemstones, quartz wafers, LED displays, liquid crystal glass, magnetic materials, semiconductors, and other valuable and fragile high-tech materials. |
