Application Case of Boron Carbide Grinding in Mudanjiang

Sapphire Wafer Grinding Application Case Studies

A leading domestic sapphire manufacturer had long relied on boron carbide from other regions for wafer grinding, with a surface‑scratch rate consistently around 3.2%—a level it was unable to reduce further. In 2025, after switching to Mudanjiang carbonized boron micro‑powder supplied by Mudanjiang Qianjin, three months of production testing revealed that the wafer surface‑scratch rate dropped to 0.8%, overall grinding efficiency improved by 12%, unit production costs fell by 8%, and the yield of its core products increased significantly—clearly demonstrating the superior performance of Mudanjiang’s boron carbide.

Case Study on Carbide Tool Grinding

A well-known manufacturer of cemented carbide cutting tools has procured Mudanjiang Boron Carbide F240‑grade products for its rough‑grinding process. Compared with the previously used equivalent product, the service life of the finished tools has improved by 15% overall, and the yield of first‑pass‑good parts in the rough‑grinding stage has increased from 94% to 98.2%. The company now saves approximately RMB 120,000 annually in consumable costs alone and has entered into an annual supply agreement with Mudanjiang Qianjin Boron Carbide, ensuring a stable procurement of its products.

Case Study in the Field of Boron Carbide Wear-Resistant Protection in Mudanjiang

Case Study of Spray-Welded Wear-Resistant Coatings on Mining Equipment

At a large open-pit mining enterprise in Northeast China, the ball mill liners were previously coated with conventional wear‑resistant coatings, requiring replacement every three months on average. Each replacement necessitated a shutdown of more than 48 hours, disrupting production schedules. After switching to a composite wear‑resistant coating made from boron carbide sourced from Mudanjiang, the liner replacement cycle was extended to 14 months, equipment downtime was reduced by 70%, and annual maintenance costs were cut by over RMB 400,000, earning high praise from the company’s production department.

Wear-Resistant Application Case for Sandblasting Nozzles

The sandblasting industry places extremely high demands on the wear resistance of abrasive nozzles. A large steel‑structure sandblasting plant previously used standard boron carbide nozzles, which had an average service life of about 72 hours. Frequent replacements not only increased labor costs but also reduced processing efficiency. After switching to nozzles manufactured from Mudanjiang‑produced boron carbide, the average service life rose to 168 hours—a 130% improvement—while the plant’s processing efficiency improved by nearly 20% and production costs were significantly reduced.

Case Study of Boron Carbide Shielding Applications in the Nuclear Industry in Mudanjiang

Case Study of Neutron Shielding Materials in Nuclear Power Plants

In a neutron‑shielding experimental project conducted by a domestic research institute, high‑purity neutron‑absorbing materials were required, with stringent specifications for product purity and isotopic composition. Ultimately, the institute procured a boron‑10‑enriched boron carbide product from Mudanjiang Qianjin Carbide, boasting a purity of 99.5%. Experimental results demonstrated that this batch achieved a neutron absorption efficiency of 96.8%, fully meeting the project’s technical requirements, and the project was successfully accepted.

Shielding Case for Nuclear Waste Storage and Transport Containers

A specialized nuclear environmental protection enterprise incorporates Mudanjiang boron carbide particles into the shielding layers of nuclear waste storage and transportation containers. The resulting products exhibit stable shielding performance that fully complies with relevant national safety standards. Compared with other similar materials, the overall weight of the shielding layer is reduced by 12%, effectively lowering logistics costs during storage and transport. Currently, the company has designated Mudanjiang boron carbide as a designated supply material.

Case Study on the Military Manufacturing and Application of Boron Carbide in Mudanjiang

Applications of Bulletproof Ceramic Armor

A domestic defense‑industry supplier requires boron carbide raw material with high hardness and excellent consistency for manufacturing bulletproof armor ceramics. Following multiple rounds of sample testing, the company ultimately selected boron carbide from Mudanjiang Qianjin, which meets its specifications. The resulting molded bulletproof ceramic exhibits uniform hardness and fully complies with national military standards, while consistent quality in mass production ensures it fully satisfies the enterprise’s large‑scale manufacturing needs.

Application Cases of Armor-Piercing Projectile Core Materials

A certain military‑industrial research institute is developing a new type of armor‑piercing projectile core and requires high‑purity boron carbide as a key component in its composite formulation. Following the selection of boron carbide from Mudanjiang, sample testing demonstrated that the core’s armor‑piercing depth performance fully meets the design specifications, thereby providing reliable material support for the project’s subsequent R&D efforts.
