Lithium Nitride can affect you when breathed in and may be absorbed through the skin. * Contact can severely irritate and burn the skin and eyes. * Breathing Lithium Nitride can irritate the nose and throat. * Lithium Nitride is a HIGHLY FLAMMABLE and REACTIVE chemical and a DANGEROUS FIRE and EXPLOSION HAZARD. Inhalation: This may irritate the upper respiratory system. Ammonia gas may irritate the nose and throat, causing dyspnea, bronchial spasms, chest pain, pulmonary edema, and frothy pink sputum—ingestion: Considered to have low toxicity by ingestion. Ammonia gas may cause nausea, vomiting, and burns. Boron in foods and beverages isn't harmful. But boron can cause harm if a person accidentally swallows cleaning products or pesticides that contain certain forms of boron, such as borax (sodium borate) or boric acid. The symptoms of too much boron include nausea, vomiting, diarrhea, rashes, headaches, and convulsions. A carbon-based material called Lonsdaleite outperforms a boron-and-nitrogen alloy called w-BN in terms of strength. The carbon-carbon bonds in Lonsdaleite are stronger than those in w-boron-nitrogen BN. Boron Nitride's hardness is second only to diamond, but it has better thermal and chemical stability; hence boron nitride ceramics are used in high-temperature equipment. Boron nitride nanotubes can have a similar structure to carbon nanotubes. Boron Nitride is an advanced synthetic ceramic material with unique properties such as high heat capacity and outstanding thermal conductivity, easy machinability, and superior dielectric strength. We generally sell Hexagonal Boron Nitride as a dry powder. Still, upon request, we can provide it as either a thick paint or thin paste (sprayable), convenient for tooling and stamping machined parts. You may order from four different pastes on this page. The hexagonal type is like graphite and is often used as a lubricant. On the other hand, cubic boron nitride is hard and chemically stable. This makes it suitable for applications requiring tough material, e.g., bulletproof products.
