Used in Ceramics Industry:
In the ceramics industry, beryllium sulfate tetrahydrate is used as a component in the manufacturing process. Its unique properties, such as its solubility in water and its ability to form different hydrate forms upon heating, make it a valuable addition to the production of certain ceramic materials.
Used in Chemical Reagents:
Beryllium sulfate tetrahydrate is also utilized as a chemical reagent in various industrial applications. Its chemical properties, including its solubility and reactivity, make it a useful compound for a range of chemical processes and reactions.
Preparation
Beryllium sulfate may be prepared by
treating an aqueous solution of any beryllium salt
with sulfuric acid, followed by evaporation of the solution
and crystallization. The hydrated product may be
converted to anhydrous salt by heating at 400°C. The
anhydrate may also be prepared by reacting the oxide
with SO2 gas at elevated temperature. Its CAS number
is 13510-49-1. If the solution method is used, a tetrahydrate
forms, (BeOH)2SO4·4H2O whose molecular
weight is 177.1462 g/mol with a CAS number of 7787-56-6.
No major commercial application of berylliumsulfate
is known and it has not been offered for sale.
Air & Water Reactions
Water soluble.
Reactivity Profile
Salts, basic, such as BERYLLIUM SULFATE TETRAHYDRATE are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Incompatible with acids.
Fire Hazard
Literature sources indicate that BERYLLIUM SULFATE TETRAHYDRATE is probably nonflammable.
Safety Profile
Confirmed carcinogen withexperimental carcinogenic data by inhalation. Deadlypoison by subcutaneous and intravenous routes. Humanmutation data reported. When heated todecomposition it emits very toxic fumes of BeO and SOx.
Purification Methods
It crystallises from weak aqueous H2SO4 and is dried in air.
Check Digit Verification of cas no
The CAS Registry Mumber 7787-56-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7787-56:
(6*7)+(5*7)+(4*8)+(3*7)+(2*5)+(1*6)=146
146 % 10 = 6
So 7787-56-6 is a valid CAS Registry Number.
