Four water was colorless transparent monoclinic crystals, α- and β- type two. Density: α- type 1.896, β- type 1.82. Melting point: α- type 42.7 ℃, β- type 39.7 ℃. Decomposition at 132 ℃. Monohydrate granular substance calcium nitrate stock, melting point of about 560 ℃. Anhydrous is a white solid, 2.36 density, melting point 561 ℃. Deliquescence in the air. When burning decomposed into calcium oxide. Dissolved in water, ethanol and acetone. Health Hazards: pathways: inhaled, ingested, percutaneous absorption. Inhalation of dust on the nose, throat and respiratory tract irritation calcium nitrate, causing coughing and chest discomfort. Eye irritation. Prolonged and repeated exposure to dust is irritating to the skin. Acute toxicity: LD503900mg / kg (rat oral) hazardous characteristics: strong oxidants. Heating decomposition and emit oxygen. Mixed with organic matter, reducing agents, combustibles such as sulfur, phosphorus or metal powders can form explosive mixtures. Combustion decomposition and emit toxic nitrogen oxides. By heat decomposition, produce toxic nitrogen oxides. Combustion (decomposition) products: nitrogen oxides. Laboratory monitoring methods: acid phenol two spectrophotometry (GB7480-87, Water) (nitrate) ion chromatography (GB13580.5-92, Water) (nitrate) Storage: packaging must be moisture-proof, sealed, not with organic matter, sulfur mixed transport. Store in a cool, ventilated warehouse Low calcium nitrate, storage temperature should not exceed 28 ℃ during transportation to prevent rain and sun exposure. Strictly prohibited and acids, flammable, organic matter, reducing agents, spontaneous combustion when wet flammable liquids and vehicle transportation mix. Colorless monoclinic crystal, soluble in water, methanol, ethanol, easily deliquescence in the air is the oxidant. 45 ℃ melting point; d1.860. Calcium nitrate is mainly used in refrigerants, rubber industrial flocculants, also used to make tubes, analytical reagents, test sulfates, oxalates. Formulated basal medium. Pyrotechnic material.
