2.Rhenate of ammonia, rhenate of potassium, oxide of calcium, oxide of molybdenum, rich-manganese slag, spiegeleisen(containing manganese), lime, lead sulfide, electrode paste.
3.To evalate the efficacy of iodoform-calcium hydroxide used as an intracanal medication in root canal therapy of deciduous teeth with periapical periodontitis.
4.Objective: To compare the clinical effects of calcium hydroxide iodoform (CHI) slurry and traditional intracanal medication such as formocresol (FC), camphophenic (CP).
5.To study the content alteration of bacterial endotoxin in the exudant from the root canals of periapical treated with calcium hydroxide as intracanal medicament.
6.To study the content alteration of bacterial endotoxin in the exudant from the root canals of periapical diseases treated with calcium hydroxide as intracanal medicament.
7.Methods dip 2% lidocaine or impede narcosis, use the acuity exonerative plane root slot cut endodontium,after drying overlay thin hydrochloride zinc and than using the zinc phosphate to mount.
8.The results of research show that the impurity of infusibility and metal ion has been removed after the leaching of calcium carbide residue, and the transform rate of hydrated lime up to about 88%.
5.The heat is applied to limestone, to break up its principal constituent, calcium carbonate, into calcium oxide (cement's crucial ingredient) and CO2.
6.The essential ingredient in cement is calcium oxide, CaO. We get that calcium oxide from limestone, which is mostly made of calcium carbonate: CaCO3.
7.Over time, some CO2 from the atmosphere drifts into all that cement in buildings and bridges, and reacts with the calcium oxide to form calcium carbonate again.
8.Limestone is refined to produce calcium oxide, or quicklime, for cement, in a reaction known as calcination, which releases a lot of carbon in the form of CO2.
石灰石被提炼以生产用于泥的氧化钙或生石灰， 在称为煅烧的反应中，该反应以 CO2 的形式释放大碳。机翻
9.The resulting calcium hydroxide reacts with carbon dioxide in the air, starting a process called autogenous healing, where microscopic calcium carbonate crystals form and gradually fill the gap.
10.But in fact, most of the CO2 emissions come not from the heating, but from the breakdown of limestone, which is calcium carbonate, into calcium oxide and carbon dioxide, or CO2.
11.It wasn't until 2004 that they found the cause of the problem was lime or calcium hydroxide, to give it its proper chemical name, which was being used in the construction of roads.
