Calcium Hydride CaH2 powder:
CaH2 Powder What does CaH2 stand for? Calcium Hydride is its chemical name. CaH2 is a Gray-white, blocky calcium hydride crystal. It can also be used as an reducing agent or desiccant. It can also be called an orthorhombic colorless crystal. In industrial products, it is gray, powder, or orthorhombic. How do you remove hydrogen gas from water? Binary hydrides, which contain only hydrogen and one additional element, are known as MH or Mh2. They can react with water vigorously by removing hydrogen gas. 15giorni has been a reliable global supplier of calcium hydride . The product does not react at normal temperatures with nitrogen or dry air. It reacts at high temperatures with these gases to make calcium oxide and calcium carbide. Water can react with hydrogen to make hydrogen or calcium glycolate when it has been decomposed. You can send us an inquiry regarding the current cost of Calcium Hydride. It is much more difficult to reduce metal oxides than either sodium hydride nor lithium hydride.
Below are basic properties and chemical characteristics of the compound.

Molar Mass : This material has a molars mass 42.094 g/mol.
Specific Gravity: This is its specific gravity of 1.9.
Melting Point: This material has a melting temperature of 816 °C.
Density: This density is 1.70 g/c3.
Advantages of Calcium Hydride
It is a popular choice as a drying agent. However, this compound has its disadvantages.
Because it is insoluble in all solvents, its drying process is slow.
It is uncompatible with many solvents. This powdered compound is incompatible with many solvents. Because CaH2, a salt-like saline hydrogenide, is calcium hydride called Hydrolith Saline hydrides are formed from the alkali, alkaline and earth metals.
This solvent cannot be used to deoxygenate because it does not remove dissolved oxygen.
Because of the similarity in appearance, it is very difficult to tell Calcium Hydride from Calcium Hydroxide.
What is the process of producing Calcium Hydride CaH2 Pulp?
Here are the specific steps required to create calcium hydride.
1. The iron plate should be filled with refined calcium, a solution of 99.5% purity. Place the iron plate with a purity of 99.5% into the water outlet and inlet pipes with rubber plugs on both ends. An electric furnace is used to heat the reaction tube. To replace the hydrogen in the reaction tube, large amounts of hydrogen are added at the beginning. Then the tubes are heated using an electric furnace. After the reaction was started at 200°C, it was heated up to 250-300°C. Finally hydrogen was introduced at an flow rate of 0.6 milliliters per minute. This reaction takes about two hours. The calcium hydride created is a porous white crystalline powder. About 99% purity is achieved.
2. Both pure electrolytic hydrogenation or alkaline Earth metal can create alkaline Earth metal hydride. This hydrogenation device is used to prepare CaH 2. It’s the same device that was used for alkali metall hydride. Vacuum distillation is required to remove the oxide layer from the metallic calcium. After that, the piece of the calcium must be removed in an operation container filled with argon. Smooth and clean surfaces are possible under the conditions of isolating the air. The boat, which is made from electrolytic Iron, contains small amounts of calcium. It is also contained within a quartz tube. A thin-walled, electrolytically iron tube covers the heating portion of the quartz tubes to protect it from calcium vapor. For the hydrogenation reaction to begin, it is necessary to first heat the calcium to 400 to 500°C. Next, cool the tube to room temperature to obtain calcium hydride. A petroleum ether bubbler can be used to verify that the hydrogenation process is completed. Pause H2. The reaction is completed if the bubble tube’s liquid level does not rise. It is a sign that hydrogenation needs to be continued if it rises in conduit liquid.
Calcium Hydride CaH2 Pulp:
In powder metallurgy CaH2 Powder is widely used. This powder can also be mixed with zirconium (niobium), hafnium, or other metal oxides to produce the appropriate metal powder. CaH2 powder is used extensively in powder metallurgy. You can combine it with zirconium or niobium to reduce the metal oxides and get the appropriate metal powder.
The use of calcium hydride is more safe than using sodium metal or sodium potassium alloy. The desiccant of calcium hydride for basic solvents, such as amines, pyridine and pyridine is widely used. It can be used to dry alcohol.
Uses for calcium hydride
This compound is used for two purposes: it can be used as both a desiccant and to make hydrogen.
Use calcium hydride in desiccant
It’s a very mild desiccant. It is therefore safer to use the compound for desiccant than more reactive agents such as sodium-potassium amalgam and sodium metallic. These are the ways it reacts to water
CaH2 + 2 H2O→Ca(OH)2 + 2 H2
This reaction produces hydrolysis products (hydrogen (gas), and Ca(OH),2 [aqueous mixture]) that can be separated from other chemical solvents through filtration, distillation or decantation.
This is an effective deiccant for alkaline solvents like amines and even pyridine. It is often used to dry solvents first before applying more reactive desiccants.
Calcium hydride used for hydrogen production
As a hydrogen source, the compound was discovered under the name Hydrolith in the 1940s. For a long period, it has been used to produce hydrogen. You can still make hydrogen from it in the lab by performing various experiments.
These two applications are not the only ones for which powdered compounds can be useful. They also serve as strong reducing agents.
Calcium Hydride CaH2 powder Storage:
