Silicon carbide ceramics are among the most competitive bulletproof ceramic materials currently available, characterized by low price, light weight, high hardness, and impact resistance. We utilize state-of-the-art pressureless sintering technology to produce high-quality products with competitive pricing and short delivery times.

Production Process: First, high-purity silicon carbide powder is mixed with a mature granulation technology formulation. Then, it undergoes molding and isostatic pressing, followed by pressureless vacuum sintering, testing, and finally packaging.

Alumina, silicon carbide, and boron carbide are three commonly used materials in bulletproof ceramics. Alumina ceramic bulletproof plates (commonly known as "white plates") have a lower hardness (HRA90) and higher density; boron carbide ceramic bulletproof plates have high hardness and low density, offering excellent performance, but are significantly more expensive than the other two materials. Compared to alumina bulletproof plates, silicon carbide ceramic bulletproof plates (commonly known as "black plates") have a hardness of HRA92 and a density of only 82%, making them more affordable and widely applicable.

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.
