A method called negative additive manufacturing is used to produce near fully dense complex shaped boron carbide parts of various length scales. This technique is possible via the formulation of a novel suspension involving resorcinol-formaldehyde as a unique gelling agent that leaves behind a homogenous carbon sintering aid after pyrolysis.

2013
Cross-conjugated cruciform fluorophores based on 1,4-distyryl-2,5-bis(arylethynyl)benzene and benzobisoxazole nuclei can be used to qualitatively identify diverse Lewis acidic and Lewis basic analytes. This method relies on the differences in emission colors of the cruciforms that are observed upon analyte addition. Structurally closely related species can be distinguished from each other.
FAQs
Its crystal structure organizes boron-rich icosahedral clusters linked by atomic chains. Strong covalent bonding holds this framework together and gives the ceramic exceptional hardness. That structural arrangement helps explain why boron carbide resists wear in abrasive powders, cutting tools, and wear-resistant components, while retaining its characteristic low density.
The combination broadens where this material can be used. Exceptional hardness and wear resistance support contact with abrasive conditions, while low density provides a lightweight counterpart to heavier materials. Chemical stability adds another useful attribute for components expected to retain performance over time, helping explain the range from protective applications to wear-resistant parts.
Boron-10 can absorb neutrons, making its presence chemically relevant to nuclear engineering. In boron carbide, this isotope-related behavior supports uses in reactor control and shielding, where neutron absorption is important. The same ceramic therefore links atomic composition with a functional nuclear role, rather than serving only as a mechanically hard material.
Exceptional hardness and wear resistance allow boron carbide to function as a demanding abrasive material. Those properties are useful when powders must withstand mechanical contact, and they also support the use of the ceramic in cutting tools. Its chemical stability further complements these mechanical advantages in components exposed to conditions that could otherwise degrade a material.
Protective armor benefits from the unusual pairing of mechanical strength and low density. Strength contributes to the material’s protective function, while low density helps limit the mass of the ceramic-based solution. The same balance is relevant to wear-resistant components, where resistance to mechanical damage is needed without discarding the material’s lightweight character.
Chemistry provides the basis for understanding both the structure and the applications. Boron-rich icosahedral clusters, atomic chains, and strong covalent bonds account for key mechanical behavior, while boron-10 introduces neutron absorption as an isotope-related function. Together, these features connect chemical composition and bonding to materials science, reactor technology, and nuclear shielding.
