The wear resistance of boron carbide is not blown. In industrial production, it is widely used in various high wear components. For example, in a waterjet nozzle, high-pressure water mixed with abrasives washes the nozzle at a speed of 800 meters per second. Ordinary hard alloy nozzles will wear out and be scrapped in no time, but boron carbide nozzles can easily withstand 200 hours and have a service life 20 times longer than ordinary nozzles! This is due to its ultra-high hardness and stable crystal structure, which makes it difficult for abrasives to damage it, greatly improving the efficiency and quality of industrial production.

Characterized by outstanding physical and chemical properties, boron carbide demonstrates

Nuclear grade boron carbide detection items: total boron, total carbon, soluble boron, boron 10 isotope analysis (mass spectrometry), free carbon, iron, aluminum, silicon, calcium, cobalt, chromium, copper, magnesium, manganese, molybdenum, phosphorus, nickel, titanium, tungsten, zirconium, fluorine, chlorine and other chemical components.

Solid state method: This method mainly uses high-temperature solid-state reaction to react boron source with carbon source at high temperature to generate boron carbide. This method is easy to operate, but requires higher temperatures and longer reaction times.

High strength and hardness: The hardness of silicon carbide ceramics is second only to diamond, with extremely high wear resistance and compressive strength, suitable for extreme working conditions.

Although traditional bulletproof ceramics have improved their bulletproof effect through certain toughening, they still have some drawbacks, such as increasing material toughness while sometimes reducing material strength. Moreover, traditional bulletproof ceramics are difficult to withstand continuous impacts, cannot be repaired after impact, are disposable, have high costs, low reliability, and do not have good structural designability.

At present, the main method for enhancing the toughness of boron carbide ceramics is to optimize the material composition, such as by increasing fiber/whisker toughening and second phase particle toughening.

The research on enhancing the toughness and improving the density of silicon carbide ceramics has been our ongoing work. The main methods for enhancing the toughness of silicon carbide ceramics are to change the composition of the ceramic material, such as by increasing fiber/whisker toughening, second phase particle toughening, and changing the ceramic forming process to change the internal microstructure of the ceramic.

In the early days, armor plates were made of homogeneous armor, and most tanks and other armored vehicles were covered with steel plates.

Sintering is a crucial step in the preparation of B4C ceramics, and the main factors affecting the sintering of B4C ceramics include sintering method
