防弹氮化硅陶瓷片

Silicon nitride ceramic bulletproof tablets are plates or tiles made from super hard silicon nitride materials, designed to be lightweight, durable, and highly effective at stopping bullets and other projectiles. They are commonly used as body armor for military and law enforcement personnel, as well as for vehicle armor and other protective applications.

描述

Bulletproof tablets are made from super-hard silicon nitride materials that have the same color and size. They have a moderate density and high bulletproof ability. All types of bulletproof tablets meet the NIJ, European, and Chinese standards, and have passed the tests of authorities.

Our ceramic bulletproof tablets have the following characteristics: good performance, lightweight, a large protective area, less striking distance, and effectively prevent bullet penetration. Meanwhile, they can avoid or significantly reduce the damage caused by bullet penetration to the human body.

Ceramic bulletproof tablets can be made into protective armor for cars and planes to deliver better performance, especially against APHE, where they have a better effect.

The high-strength properties of silicon nitride ceramic make it an excellent material for bulletproof applications. It has a high fracture toughness, which means it can withstand high amounts of stress without cracking or breaking. It also has a high melting point and can resist deformation even when exposed to high temperatures.

Silicon nitride ceramic bulletproof tablets are commonly used in body armor for military and law enforcement personnel, as well as for vehicle armor and other protective applications. They offer superior protection against high-velocity projectiles and are often used in conjunction with other materials to provide multi-hit protection.
