From Powder to Power: Advanced Ceramic Armor Solutions
B4C (Boron Carbide)

Boron Carbide is the third hardest material known, surpassed only by diamond and cubic boron nitride. Not only does it possess extraordinary hardness, but it's also one of the most challenging materials to produce globally. With a density of 2.52 g/cm³, boron carbide is the lightest, thus the easiest to carry, ballistic armor plate. Its hard surface, fortified by robust chemical bonds, reduces wear in harsh environments.
At Nurol Teknoloji, we leverage boron carbide, a derivative of the boron mine - with 70% of the world's reserves in our country, to produce the lightest, highest quality ballistic ceramics. We employ Reaction Bonding method to manufacture boron carbide ballistic armor plates. Furthermore, we have developed boron carbide composite ceramics through the direct sintering method, making us the highest-capacity producer worldwide with our experienced technical team and professional equipment.
AI2O3 (Alumina)

Aluminum Oxide, or Alumina, is a versatile ceramic material known for its exceptional hardness and strength. It exhibits high thermal conductivity, electrical insulation, and excellent resistance to wear and corrosion, making it suitable for numerous demanding applications. Alumina, with a theoretical density of 3.98 g/cm³, is renowned for maintaining its high strength and reliability even under extreme conditions such as high temperatures and corrosive environments.
In the realm of ballistic protection, Alumina ceramic armors present an ideal solution for clients seeking cost-effective yet highly effective defense against a range of threats. Alumina's unique properties, including its wear resistance and ability to withstand high temperatures, make it suitable for armor applications. At Nurol Teknoloji, we utilize cutting-edge manufacturing processes to produce Alumina ceramics in various sizes, geometries, and thicknesses, providing our customers with protection solutions tailored to their unique requirements.
SiC (Silicon Carbide)

Silicon Carbide, the ceramic material with the highest hardness after boron carbide, exhibits excellent wear and corrosion resistance, even at high temperatures. It also has superior thermal conductivity, thermal shock resistance, and minimal thermal expansion. With a theoretical density of 3.2 g/cm³, silicon carbide ceramic armors offer protection against high threats with low weight, making it an ideal choice for personal protection, military vehicle armor, and structural protection systems.
At Nurol Teknoloji, our furnaces operating in an inert gas atmosphere at 2250°C empower us to manufacture SiC technical ceramics in various sizes, geometries, and thicknesses.
SiC/B₄C Hybrid (Silicon Carbide / Boron Carbide)

SiC/B₄C hybrid powder, obtained by combining Silicon Carbide (SiC) and Boron Carbide (B₄C) at a 60/40 ratio, brings together the superior properties of both materials in a single formulation. The high thermal stability of SiC combines with the low density and exceptional hardness of B₄C to create an ideal material for ballistic protection, wear resistance, and lightweight armor applications. With its high mechanical strength, low density (2.8–2.9 g/cm³), and superior wear performance, this hybrid powder offers a wide range of applications, from military armor systems and industrial wear plates to protective ceramic components and nuclear applications.
At Nurol Teknoloji, we process SiC/B₄C hybrid powder in our furnaces operating at 2050–2150°C under an inert gas atmosphere to produce high-precision ceramic components.
