New development of production technology of boron carbide nozzle
1. In terms of powder preparation, the most noticeable current research is the manufacturing technology of high-purity ultra-fine boron carbide powder. High-purity ultra-fine boron carbide powder is a necessary basic material for the manufacture of boron carbide special ceramics, such as boron carbide ultra-fine powder, boron carbide nano powder, boron carbide nuclear powder, boron carbide fiber, boron carbide whisker, medical boron carbide dressing, etc. . Manufacturing technology of high-purity ultra-fine boron carbide powder, which can prepare boron carbide to a degree of fineness and purity that cannot be processed by conventional methods, obtain ultra-fine and high-purity boron carbide, improve the production efficiency of boron carbide ceramics, and make it press-processed The procedures have become simplified and easy to implement, which is conducive to the rapid development of the production of boron carbide products.
In addition, in recent years, some people have also studied the preparation of boron carbide nozzles by using methods such as dissolving powders, chemical vapor deposition ceramic powders, and plasma vapor phase reaction methods to make up for the difficulty of powder collection.
In short, in the past few years, the preparation technology of boron carbide high-purity and ultra-fine powder has made great progress, but the cost is too high, and the quality of the powder is not stable enough. We still need to strengthen research to make these problems well resolved.
