Calcium nitrate, molecular weight 164.09. Colorless cubic crystal, density 2.504g / cm, a melting point of 561 ℃, in the air deliquescence, soluble in water. Can form monohydrate and tetrahydrate. Wherein Ca (NO3) 2 · 4H2O, molecular weight 236.15, colorless crystals, deliquescent, soluble in methanol and acetone. Wherein the α- type, density 1.896g / cm3 calcium nitrate content, melting point 42.7 ℃; β- type, density of 1.82g / cm3, a melting point of 39.7 ℃, decompose at 132 ℃, monohydrate granular substance, melting at about 560 ℃. First aid measures: Skin contact: Remove contaminated clothing Shandong calcium nitrate, with plenty of water. Eye contact: Did eyelid calcium nitrate wholesale, with the flowing water or saline. Medical treatment. Inhalation: rapidly from the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, artificial respiration immediately. Medical treatment. Ingestion: drink enough water, the symptoms. Medical treatment. Fire fighting methods: firefighters are required to wear gas masks, body wear firefighting suits. Mist with water, sand fire. Do not flow directly from radio to melt, to avoid serious fire or the flow causes intense boiling splash. Urea and ammonium bicarbonate nitrogen losses during storage and use of 40-50% per year due to the loss of nitrogen caused by environmental pollution is very serious. Thus calcium nitrate, improve fertilizer utilization and protection of the environment has become a crucial issue of agricultural development. Soil nitrate containing calcium nitrate without being transformed apples can be absorbed directly, small volatilization loss of nitrogen, as basal and top dressing fertilizer it fast, you can quickly make apple nitrogen, is a highly efficient environmentally friendly fertilizer, in the apple production It has good promotion prospects and value. _ Three calcium nitrate content level of chemical quality assurance (certification) _ calcium nitrate provided by the Jinan Chemical Co., Ltd. three levels. Jinan three ping Chemical Co., Ltd. (www.sanpinghuagong.com) Shandong Jinan, chemical products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Three-ping Chemical leadership with the staff warmly welcome all inquiries negotiations to create three levels of chemical better future.
