Silicon Carbide Ceramic Silicon Carbide bulletproof ceramics

    Product Details

    Silicon carbide ceramics are currently the most competitive product among bulletproof ceramic materials, with characteristics such as low price, light weight, high hardness, and impact resistance. We use the most advanced pressureless sintering process to prepare products with good quality, competitive price, and short delivery times.

    Production process: Firstly, it is made by mixing high-purity silicon carbide powder with the most mature technical formula for granulation, followed by molding and isostatic pressing, pressureless vacuum sintering, testing, and finally packaging. 

    Aluminum oxide, silicon carbide, and boron carbide are three commonly used materials in bulletproof ceramics. Alumina ceramic bulletproof sheet (commonly known as white sheet) has low hardness (HRA90) and high density among the three; Boron carbide ceramic bulletproof sheets have high hardness, low density, and the best performance among the three materials, but their prices are also far higher than the other two materials. Compared to aluminum oxide bulletproof sheets, silicon carbide ceramic bulletproof sheets (commonly known as black sheets) have a hardness of HRA92 and a density of only 82%, making them more affordable and widely used.

    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.

    Product Application

    Bulletproof armor plate: Silicon carbide ceramics can be made into bulletproof armor plates, which are used for the protection of vehicles, aircraft, and ships, providing effective bulletproof capabilities.

    Bulletproof shields and vests: Silicon carbide ceramics can be made into bulletproof plates for bulletproof shields and vests, providing personal protection and protecting soldiers and safety personnel from bullet injuries.

    Bulletproof windows and protective walls: Silicon carbide ceramics can be used to manufacture bulletproof windows and protective walls, providing bulletproof protection for buildings and facilities.
