(1) A trivalent metalloid element; occurs both in a hard black crystal and in the form of a yellow or brown powder
(1) The mineral elements most likely to be deficient in vineyards are nitrogen, potassium, phosphorus, zinc, boron , iron, manganese, and magnesium.
(2) Nitrogen, phosphorus, potassium, sulphur and boron have been found to be important in Zambia.
(3) The smaller element may be a nonmetallic element, such as boron , carbon, nitrogen, or silicon.
(4) Trace minerals that are already more than adequate in most diets include phosphorus, iodine, manganese, chloride, molybdenum and boron .
(5) Grain refinement by titanium, boron and zirconium additions has only a limited effect on mechanical properties.
(6) Electrons from the n-type half are drawn to the p-type half because of the way that phosphorus and boron bond with silicon.
(7) This product is a laundry aid containing sodium, boron , oxygen, and water.
(8) Those with less than an octet are often called electron deficient and are typical of certain elements with an odd number of electrons, such as boron and nitrogen.
(9) Zinc is in solid solution; boron , titanium and zirconium are seldom added in amounts sufficient to produce visible compounds.
(10) The most widely used grain refiners are master alloys of titanium, or of titanium and boron , in aluminum.
(11) In certain cases, small metallic atoms, like boron and beryllium, may enter into restricted interstitial solid solutions.
(12) They spray boron and energetic nitrogen atoms onto a clean, heated tungsten surface, held at 250 to 500 volts, in an ultrahigh vacuum.
(13) In addition, soy also contains magnesium and boron , which are important co-factors of calcium for bone health.
(14) Diffusion methods modify the chemical composition of the surface with hardening species such as carbon, nitrogen, or boron .
(15) It was not until 1807, however, that Sir Humphrey Davy identified boron as a chemical element.
(16) The immobile nutrients are iron, sulfur, calcium, manganese, copper, zinc, boron , molybdenum, and chlorine.
(17) Each layer is doped with tiny amounts of different impurities, usually phosphorus and boron .
(18) Nitrogen and boron are increasingly used in steels in small but significant concentrations.
(19) Besides hydrogen and its isotope deuterium, researchers use the isotopes of boron , oxygen, nitrogen and carbon.
(20) These rare coloured stones are highly treasured; their coloration comes from traces of elements such as boron and nitrogen or from structural flaws in the crystal lattice.
(21) Some clues can be found in erbium rhodium boride and holmium molybdenum sulphide — the superconductivity of both these materials is destroyed by the onset of a first-order ferromagnetic phase transition.
(22) Possible ceramics for such armours are: Boron carbide, Silicon carbide, Aluminium oxide, or Titanium boride .
(23) Either calcium boride or lithium should be plunged into the molten bath to deoxidize the melt.
(24) Some borides exhibit very useful physical properties.
(25) Six months ago, researchers worldwide were thrilled by the discovery that magnesium boride became superconducting at a temperature higher than traditional theories predicted was possible.
