• 説明

  Calcite is one of the most common minerals on the face of the earth, comprising about 4% by weight of the earth’s crust and is formed in many different geological environments. Calcite can form rocks of considerable mass and constitutes a significant part of all three major rock classification types. It forms oolitic, fossiliferous and massive limestones in sedimentary environments and even serves as the internal cement for many sandstones and shales.Calcite is even a major component in the igneous rock called carbonatite and forms the major portion of many hydrothermal veins. Not necessarily a variety of calcite, cave formations are certainly a unique aspect of calcite’s story.

• 化学的特性

  Calcium carbonate is a white, odorless powder, or crystalline solid.

• 使用

  Source of lime; neutralizing agent, filler, and extender in rubber, plastics, paints; opacifying agent in paper; fortification of bread; putty; tooth pow- ders; antacid; whitewash; Portland cement; sulfur dioxide removal from stack gases; metallurgical flux; analytical chemistry; carbon dioxide gener- ation (laboratory).

• 製造方法

  The calcite present is derived mostly from the remains of organisms such as clams, brachiopods, bryozoa, crinoids and corals. These animals live on the bottom of the sea and when they die their shells accumulate into piles of shelly debris. This debris can then form beds of limestone. Some limestones may have been derived from nonbiogenic calcite formation.

• 定義

  Aragonite: An anhydrous mineral form of calcium carbonate, CaCO₃, which occurs associated with limestone and in some metamorphic rocks. It is also the main ingredient of pearls. It is not as stable as calcite, into which it may change over time.
  Calcite:A mineral form of calcium carbonate occurring in limestone, chalk, and marble.
  Charlk: A natural form of calcium carbonate (CaCO₃) formed originally by marine organisms. (Blackboard chalk is calcium sulfate, CaSO₄.).

• 一般的な説明

  Odorless, white to tan powder.

• 反応プロフィール

  CALCIUM CARBONATE has generally low chemical reactivity. Is non-combustible. Decomposes at high temperature (825°C) to give gaseous carbon dioxide and calcium oxide (quicklime). Incompatible with acids, alum, ammonium salts, fluorine, magnesium. Reacts with acids and acidic salts to generate gaseous carbon dioxide with effervescence (bubbling). The reaction is rapid and exothermic with concentrated solutions of acids. The efferversence can create extensive foaming. Ignites on contact with fluorine.

• 危険性

  A nuisance particulate dust.

• 健康ハザード

  Calcium carbonate is considered to be a nuisance dust.
  Although no adverse effects have been reported in the literature among workers exposed to calcium carbonate, high concentrations of the dust would be expected to act as a physical irritant to the eyes and skin.1 Fourteen British workers exposed to heavy calcium carbonate concentrations for 12–35 years showed no trace abnormalities due to dust or any clinical sign of pneumoconiosis or chronic bronchitis on X ray.2 Long exposure to high dust concentrations of pure calcium carbonate (quartz content less than 1.1%) did not result in lung fibrosis.

• 化学性质

  弱碱性物质，可以与酸反应

• 农业用途

  Limestone or dolomite, used in agriculture for liming the soil, is ground to a fineness to ensure that 50% of the particles pass through a 1.70mm Indian Standards (IS) sieve, and 50% is retained on a 150micron IS sieve.

• 安全性プロファイル

  A nuisance dust. An eye and skin irritant. Igmtes on contact with F2. Incompatible with acids, ammonium salts, (Mg + H2). Calcium carbonate is a common air contaminant. See also CALCIUM COMPOUNDS.

• 職業ばく露

  Calcium carbonate is used as a source of lime; neutralizing agent; manufacturing or rubber, plastics, paint and coatings; sealants, paper, dentifrices, ceramics, putty, polishes and cleaners, insecticides, inks and cosmetics; whitewash; Portland cement; antacids; analytical chemistry, and others

• 合成方法

  天然石灰石经过破碎和磨粉处理

• 不和合性

  Calcium carbonate decomposes in high temperature forming carbon dioxide and corrosive materials

• 廃棄物の処理

  Landfills. It is the responsibility of chemical waste generators to determine if a discarded chemical is classified as a hazardous waste. See 40 CFR Parts 261.3 for United States Environmental Protection Agency guidelines for the classification determination. In addition, in order to ensure complete and accurate classification, waste generators must consult state and local hazardous waste regulations.
