What is calcium hydride? Calcium hydride is a chemical substance. Generally, the laboratory uses Ca and H2 to react under heating conditions to generate CaH2; CaH2 is a compound composed of ions. The Chinese name of CaH2 is calcium hydride. The molecular formula of CaH2 is CaH2, gray white crystal or block, which is easily deliquescent, molecular weight is 42.10, melting point: 675 ℃ (decomposition), insoluble in carbon disulfide, slightly soluble in concentrated acid, relative density (water=1) 1.7, main use: as reducing agent, drying agent Chemical analysis reagents, etc.
Safety of calcium hydride The chemical reaction activity is very high. It reacts with moisture, water, or acids, releases hydrogen, and can cause combustion. It reacts violently with oxidants and metal oxides. In the case of moisture and water, hydroxide is formed, which is highly corrosive. For glass bottle packaging, the net weight of each bottle is 500g, concentrated on the liner in the wooden box or airtightly sealed with a metal barrel lined with a polyethylene bag, and the net weight of each barrel is 25kg. The package shall be marked with "moisture proof" and "flammable." Hazardous Code No.: flammable substances in case of moisture. GB 4.3 43020. UN N0.14040 IMDG CODE 4337, category 4.3. Toxicity and protection: This product strongly irritates mucous membranes, the upper respiratory tract, eyes, and skin. After inhalation can cause death due to spasm, inflammation, edema, chemical pneumonia, or pulmonary edema of the larynx and bronchus. Contact may cause a burning sensation, cough, wheezing, laryngitis, shortness of breath, headache, nausea, vomiting, etc. The dust strongly irritates the eyes, nose, skin, and respiratory system, and the calcium hydroxide generated in case of moisture, or moisture is highly corrosive.
Synthesis of calcium hydride Put the refined calcium with a purity of about 99.5% into the iron plate and place it in the center of the quartz reaction tube. Install the inlet and outlet pipe at the two ends of the quartz reaction tube with rubber plugs, respectively. Purify the hydrogen from the inlet pipe. The outlet pipe is connected to the ventilation kitchen through the mineral oil bubbler. An electric furnace heats the reaction tube. The purified hydrogen is replaced by a large amount of hydrogen at the beginning to replace the air in the reaction system and then heated by an electric furnace. The reaction starts at about 200 ℃ and is heated to 250~300 ℃. The reaction is carried out by introducing hydrogen at a flow rate of 0.6 m1/min, which can be completed after about 2 hours. The calcium hydride produced is a porous gray-white crystalline powder, and the purity of calcium hydride is about 99%.
Price of calcium hydride Calcium hydride particle size and purity will affect the product's price, and the purchase volume can also affect the cost of calcium hydride. A large amount of large amount will be lower. The price of calcium hydride can be found on our company's official website.
