Boron Carbide Ceramic-Hot Pressed B4C bulletproof ceramic
Product Details
Boron carbide blocks used for level NIJ III and NIJ IV bulletproof protection. The product adopts a pressureless sintering process and can be made into blocks of different sizes such as squares, hexagons, triangles, etc. according to your needs, which are used to splice into a full face bulletproof plate.
The product can be made into flat and curved surfaces, with a customizable size range of 10-500mm and a customizable thickness range of 0.2-80mm.
Compared with several bulletproof ceramics that have been widely applied in protective equipment, boron carbide (B4C) ceramics have the highest hardness and lowest density, making them the most ideal armor ceramic material in terms of performance. With the increasing demand for lightweight and high protection applications in human protective equipment and the smooth promotion of B4C ceramic industrialization, B4C has been applied as one of the mainstream ceramic materials for preparing bulletproof clothing inserts.
As a reinforced protective component of bulletproof vests, high-quality bulletproof inserts are composed of B4C ceramic plates and ultra-high molecular weight polyethylene fiber composite material plates. The basic protection principle is to use B4C bulletproof ceramics to passivate and erode bullets, and then use fiber composite materials to absorb residual impact kinetic energy. According to the different application environments and protection requirements, B4C ceramic plug-in boards are divided into two types: multi curved integral ceramic boards and single curved small ceramic splicing boards.

Company Introduction
Shandong Huayi Tech New Materials Co., Ltd. is located in China and was established in 2018. The company is committed to the development and application of materials such as silicon carbide and boron carbide in multiple industries.
The company's main products are silicon carbide powder and ceramics, boron carbide powder and ceramics, silicon carbide ceramic films, nuclear power boron carbide materials, etc. These products are widely used in the nuclear power industry, military industry, environmental protection, new energy, chemical industry and other fields.
Regarding the production of ceramics, the company has two processes: pressureless sintering and hot pressing sintering. Products with different processes have different advantages and are suitable for different scenarios. Non pressure sintered ceramics have high cost-effectiveness and are suitable for mass production. They are suitable for use as bulletproof materials, seals, nozzles, wear-resistant and temperature resistant materials, as well as common nuclear power materials. Ceramics produced by hot pressing sintering are suitable for small-scale production, can be made into larger sizes, and are suitable for use as nuclear power core materials, semiconductor materials, target materials, and bulletproof materials.
