For example, Lyncole starts with a high-quality, two-inch-diameter copper tube with an exothermically welded pigtail.
They contain varying amounts of the clinker compounds: calcium oxide, 60.20% to 63.85%; silicon dioxide, 19.90% to 21.08%; and alkali oxides, 1.4%.[4] Calcium oxide (65% of the total weight) reacts with water exothermically to form calcium hydroxide [[Ca(OH).sub.2]], which may produce caustic burns to the skin.
One major advantage of magnetite is that it oxidises exothermically so that, in the pelletising process, 62% of the energy needed is generated through magnetite oxidation, while only 38% comes from external fuels such as coal or oil.
The solution was prepared at least 1 day prior to its use to allow the exothermically heated liquid to cool to ambient temperature.
The reaction proceeded exothermically and the product was analyzed using [.sup.13]C NMR and FTIR spectroscopy.
