(Zr[B.sub.2]) is a new type of ceramic material, whose lamellar crystal structure is similar to graphite, exhibiting high performance including high melting point (>3,000[degrees]C), high hardness (36.0 GPa), high elastic modulus (around 500 GPa) and good friction performance [12,13].
and Zare A.: "An effective method for increasing the activity of nickel boride
catalyst nano-particles in hydrogenation reactions: low-temperature hydrogen treatment".
This method is usually applied for producing the nanocomposite coatings with Niken matrix and nanofillers are carbide, nitrite, boride
, or PTFE [49, 81, 82, 111-117].
"CSX has repeatedly failed to deliver the total number of cars requested on the dates promised," wrote Boride
. "Additionally, CSX has begun limiting us to five cars per week.
have attracted much experimental and theoretical research because of their unique properties such as high melting point, high hardness, high elastic modulus, good thermal and electrical conductivity, excellent oxidation resistance, and considerable chemical stability .
Textured factor can be used to intensify boriding in the formation of hardened layers based either on titanium boride
, or on a solid boron solution in titanium.
Meyer, Stollwerck, and Reichenauer developed a polymer composition that absorbs infrared radiation using a boride
Chemoselective reduction of [alpha], [beta]-unsaturated aldehydes, ketones, carboxylic acids and esters with nickel boride
Kaptay and Kuznetsov reported that the boron components are dissolved in ionic form in the melt, to form boride
phase on the cathode joint with metal cations .
stated that Co-B catalyst, a black solid, could be classified in two categories as cobalt boride
([Co.sub.x]B) and cobalt-boron alloy (Co-B).
