CaH2 Calcium Hydride Powder:
CaH2 Powder Calcium Hydride is the chemical name. CaH2 is a Gray/white crystal that can be blocky or crystallized. It's used for reducing agents, desiccants, chemical analysis, etc. Also known as colorless orthorhombic Crystal; Industrial products are either gray, orthorhombics, or powder. What is the type of bond in calcium hydride Ionic hydroides react violently with water when they remove hydrogen gas. Binary hydrides, which are composed of hydrogen and only one other element, have the general designation MH2 or MH3. Examples include sodium hydride(NaH), LiH2, calcium hydride(CaH2) & magnesium hydride(MgH2). It is sensitive to moisture. Calcium Hydroide is a leading Calciumhydride supplier . It doesn't react with nitrogen or chlorine when heated to normal temperature. However, at high temperatures it will react with these gases and form calcium carbide, calcium chloride, and calcium oxide. The reaction can occur when the water is broken down and released hydrogen. This then reacts with ethanol and forms calcium glycolate. Please feel free to contact us at any time for the latest Calcium Hydride price. The metal oxides reduce more than sodium or lithium hydride.

The Disadvantages Of Calcium Hydride
This chemical compound can be used to dry products, but has some disadvantages.
This compound is a slow-drying compound because it is not soluble with any solvent that does not cause a violent reaction.
This powdered substance is incompatible with a wide range of solvents. This compound can cause explosive reactions when it reacts with chlorocarbons. Why is calcium hydrolith called Hydrolith? CaH2 hydrate is also known as Hydrolith. It is a salt-like hydride. Saline hydrides are formed by alkali metals, alkaline Earth metals, and other metals.
This product cannot be used to deoxygenate solvents because it does not remove dissolved air.
Due to their similar looks, it is very difficult to differentiate between Calcium Hydride & Calcium hydroxide.

How does Calcium Hydride CaH2 Powder get made?
Following are the specific steps involved in making calcium hydride.
1. Place the iron plate with refined calcium that is 99.5% pure in the middle of the quartz tube. Install the rubber plugs for the water outlets and inlet pipes on both ends of your quartz reaction tube. Then purify hydrogen gas using the water outlet and inlet pipes. Finally, connect the mineral oil bubbler from the outlet pipe to the fume-hood. What occurs when calcium hydroide reacts to water? When Calcium Hydride (CaH2) is vigorously reacted with water it releases hydrogen gas. The activation energy for the hydrolysis of CaH2 is lower than other reactions. Electric furnaces are used to heat up the reaction tube. A large amount of purified hydrogen will be introduced into the reaction system to replace air at first, followed by heating with an electric oven. The reaction began at around 200degC. After heating to 250-300degC the hydrogen was added at a rate of 0.6ml/min. The reaction is completed in 2 hours. The calcium hydroide produced is an off white crystalline powder. Its purity is approximately 99%.
2. Alkaline metal and pure hydrogenation electrolytic can be used to produce alkaline metal hydride. CaH 2 is prepared with the same hydrogenation apparatus as alkali metallic hydride. For the purification of metallic calcium, the vacuum distillation process must be repeated. After that, the oxide layer is removed from the surface in a box filled with liquid argon. When air is removed, the surface appears smooth and clean. A boat made of iron electrolytic is used to contain small metal calcium. The boat is then enclosed within a quartz tube. To protect the quartz tube against corrosion by calcium vapour, the heating part is covered by a thin-walled electrolytic tube. Pure hydrogen is added, and the calcium is then heated to 400 to 500degC, to begin the hydrogenation reaction. Finally, the temperature is raised to 1000degC. Calcium hydride can be obtained after the reaction has been completed by cooling it to room temperatures. To check if the hydrogenation has completed, you can use a petroleum bubbler. Pause H2. Pause H2. If the liquid in the conduit is rising, then the hydrogenation process must still continue.

Application for Calcium Hydride Powder CaH2:
CaH2 powder is used for powder metallurgy. Zirconium oxide, niobium oxide, hafnium oxide and other metals can be reduced and the metal powder obtained. CaH2 powder can also be used for generating light hydrogen to dehydrate, hydrogenate, condense or desiccate organic compounds. For what is calcium hydroide used?
Its use can be safer than other more reactive agents, such as sodium metal alloy or sodium-potassium. It is used widely as a desiccant in basic solvents, such as amines and Pyridine. It is used to dry alcohol.
Calcium Hydride Uses
The compound has a dual purpose: it can be used to create hydrogen or as a dehydrator.
Calcium hydride used as desiccant
It is a relatively gentle desiccant. This compound is less reactive than other desiccant compounds such as sodium-potassium and sodium metal. It reacts with the water in two ways:
CaH2 + 2 H2O-Ca(OH)2 + 2 H2
By filtration, decantation, or distillation you can separate the hydrolysis product of this reaction, which is Ca(OH2)2 and hydrogen (gas).
This compound can be used to desiccate many alkaline solvents, such as amines or pyridine. Sometimes used to dry solvents in advance of using more reactive desiccants.
Uses of calcium hydride in hydrogen production
As a hydrogen-source, it was sold under the brand name "Hydrolith". For a long period of time, it has been used to produce hydrogen. In many experiments, pure hydrogen is produced in the lab using this material.
This powdered compound has two other uses: it is a strong reducer.

Condition of Storage for Calcium Hydride Powder CaH2:
CaH2 powder's dispersion and use will be affected if it is damp. Calcium Hydride CaH2 must be packed in vacuum and kept in a cool, dry place. CaH2 should not be exposed to stress.

Packing & Shipping of Calciumhydride CaH2 Powder
