  • copper indium gallium selenide solar cells

    a copper indium gallium selenide solar cell or cigs cell, sometimes ci g s or cis cell is a thin-film solar cell used to convert sunlight into electric power. it is manufactured by depositing a thin layer of copper, indium, gallium and selenium on glass or plastic backing, along with electrodes on the front and back to collect current. because the material has a high absorption coefficient .

  • molybdenum diselenide

    molybdenum diselenide mose 2 is an inorganic compound of molybdenum and selenium.its structure is similar to that of mos 2. compounds of this category are known as transition metal dichalcogenides, abbreviated tmdcs.these compounds, as the name suggests, are made up of a transition metals and elements of group 16 on the periodic table of the elements. .

  • fertilizer

    in rare cases, fields are treated with the crushed mineral, but most often more soluble salts are produced by chemical treatment of phosphate minerals. the most popular phosphate-containing minerals are referred to collectively as phosphate rock. the main minerals are fluorapatite ca 5 po 4 3 f cfa and hydroxyapatite ca 5 po 4 3 oh.

  • hafnium

    hafnium carbide is the most refractory binary compound known, with a melting point over 3890 c, and hafnium nitride is the most refractory of all known metal nitrides, with a melting point of 3310 c. this has led to proposals that hafnium or its carbides might be useful as construction materials that are subjected to very high temperatures.

  • abundance of elements in earth's crust

    the abundance of elements in earth's crust is shown in tabulated form with the estimated crustal abundance for each chemical element shown as mg/kg, or parts per million ppm by mass 10,000 ppm = 1% - the mass fraction of the element in the earth's crust, multiplied by the mass of the earth's crust. note that the noble gases are not included, as they form no part of the solid crust.
