Boron manganese containing

In addition to these principal alloying elements, which provide soHd solution strengthening and/or precipitation strengthening, wrought alloys may contain small amounts of titanium and boron [7440-42-8J, B, for control of ingot grain size, and ancillary additions of chromium, manganese, and zirconium to provide dispersoids. AH commercial alloys also contain iron and siUcon. 

The conjugate acid of [MntCO) ]" HMnfCO) , protonates BjH, to give 2,2,2-(CO)3-2-MnB5H,o that contains two Mn — H—B bonds as well as a direct Mn—B bond between the apical boron atom and manganese. ... 

Ferro-alloys Master alloys containing a significant amount of bon and a few elements more or less soluble in molten bon which improve properties of bon and steels. As additives they give bon and steel better characteristics (increased tensile sbength, wear resistance, corrosion resistance, etc.). For master alloy production carbothermic processes are used for large-scale ferro-sihcon, ferro-chromium, ferro-tungsten, ferro-manganese, ferro-nickel and metallothermic processes (mainly alumino and sihco-thermic) for ferro-titanium, ferro-vanadium, ferro-molybdenum, ferro-boron. 

Steel is an alloy containing chromium, manganese, molybdenum, nickel, vanadium and boron. Copper-nickel alloy, bronze and aluminium alloys are used in making coins. Fusible alloys having low melting points are used as solder and fuses in electrical circuits. 

The first metallocarborane of this geometry to be synthesized was an unexpected product. In an attempt to prepare a ten-vertex manganese carbonyl complex, the C2B7Hii2 ion, discussed in Section VII, was reacted with BrMn(CO)5. Surprisingly, the only metal-containing compound isolated from the reaction mixture had just 6 boron atoms (36, 50). The course of the reaction may be outlined as follows ... 

The 12-heteropolymolybdates reported earlier to contain manganese and boron as the central atoms probably do not exist93,94). 

Bark contains 2-5% inorganic solids of the dry bark weight (determined as ash). The metals are present as various salts including oxalates, phosphates, silicates, etc. Some of them are bound to the carboxylic acid groups of the bark substance. Calcium and potassium are the predominating metals. Most of the calcium occurs as calcium oxalate crystals deposited in the axial parenchyma cells. Bark also contains trace elements, such as boron, copper, and manganese. 

Steels are basically classified as carbon and alloy steels which are defined by national and international standards, e.g., ASTM and DIN. Carbon steels contain less than 1.65% manganese, 0.6% silicon, 0.6% copper, plus boron and deoxidizers as well as carbon as the principal additive increasing hardness. Manganese also... 

Many products beginning to add magnesium, boron, zinc, copper, and manganese, and adding "Plus" or "Ultra" to name. Also contains vitamin K. 

Also contains magnesium, zinc, copper, boron, and manganese.
