China Half Quadrilateral Sintered Silicon Carbide Bulletproof Ceramic

Our company specializes in manufacturing physical protection bulletproof ceramic products of various materials, such as alumina, silicon carbide, boron carbide, etc. A bulletproof ceramic plate made of flat or arc plate can be used for composite body protection with insert and back plate. We also have large & whole plates with single-curved surface of bulletproof ceramic.
As the quadrilateral , 50*25,radian R400,it's specially used for human body protection with insert plate of small pieces cobbling bulletproof ceramic, and it has reached the standard NIJIIIA,NIJ III,NIJIII+,NIJ IV. It can be used for cobbling multi-surface plate, a small degree of deformation, uniform thickness, small tolerance. So the bulletproof performance of our bulletproof insert plate has greatly improved. The bulletproof insert plate made of arc plate bulletproof ceramic made by our company has passed the bullet-tests for many times, and even if the bullet hits the leaky joint, it can still be prevented.
Our company is the earliest bulletproof ceramic manufactures at home, and the products with stable quality, high hardness, moderate density, small tolerance, strong supply capacity, comprehensive range. Products are exported to all over the world, enjoy a high international reputation.
There are 6 sets of spray drying tower , 20 sets of all kinds of pressure machines, 17 sets of vacuum sintering furnaces in our company. It's annual output can reach 300 tons alumina protective ceramic,300 tons silicon carbide protective ceramic,60 tons boron carbide protective ceramic.
Sizes. Our normal specifications are as below:
Sintered silicon carbide (SiC) ceramic is a new kind of bullet-proof ceramic material, with low density, high strength, high hardness, high temperature resistance, oxidation resistance, corrosion resistance and other excellent performances. Now it's the preferred general material for bulletproof ceramic pieces, mechanical seals, sand jets as well as magnetic pumps, shielding pump components, etc.
We produce sintered silicon carbide ceramics taking high purity sub-micron silicon carbide powder as raw material, according to the advanced formula imported from Japan, through the spray granulation, pressure molding and high temperature vacuum sintering. As the structure inside is compact, small grains, bullet-proof performance of this product is superior. The breast armor plates made of silicon carbide from our company have reached the standard NIJ0101.06III,IVand passed the grade IIIV bullet-tests held by National Bulletproof Equipment Testing Center for many times. Furthermore this product has successfully passed the target test certificated by the PLA. Nowadays the PLA troops are equipped with this ceramics composite armor.
