Manufacturing High-Efficiency Drilling Tools (Drill Bits): Boron-doped diamond is commonly used to manufacture drag bits and impregnated bits. For instance, in oilfield drilling, boron-doped black polycrystalline diamond bits can efficiently drill through hard rock formations like hard limestone and gravel, and the mechanical penetration rate can be more than twice that of ordinary polycrystalline diamond bits. When drilling into rocks like dolomite marble, the drilling efficiency is significantly improved, and the cost is greatly reduced.
Producing Durable Cutting Tools (Circular Saw Blades): Leveraging its high wear resistance and excellent self-sharpening properties, boron-doped diamond is made into circular saw blades widely used for cutting high-hardness and brittle materials such as high-voltage electrical porcelain (containing corundum), optical glass, granite, and marble. Compared to ordinary diamond saw blades, its cutting efficiency is greatly enhanced, its service life is extended by several times, and processing costs are significantly reduced.
As High-Performance Cutting Tools: Boron-doped polycrystalline cutting tools are highly effective in machining metal and non-metal materials (such as fiberglass and powder titanium alloys). Due to its surface chemical inertness, when cutting iron-group metals like high-hardness quenched steel, it not only prevents the workpiece from burning but also completely avoids "sticking" and the formation of built-up edges, thereby significantly improving the machining quality of the workpiece and the durability of the toolManufacturing High-Efficiency Grinding Tools (Abrasives): Boron-doped diamond abrasives are particularly suitable for grinding hard, tough, and difficult-to-machine materials. When grinding hard alloys, its efficiency is about 30% higher than that of ordinary diamond abrasives. For specific workpieces like fuel injector nozzles, its efficiency can even be several times that of ordinary diamond or CBN (cubic boron nitride) abrasives.
Applications in the Electronics Industry (Semiconductor Materials): Because the introduction of boron atoms gives the crystal excellent hole-conducting characteristics, blue boron-doped diamond crystals are directly used as semiconductor materials in the electronics industry.
