Description
Barium metaphosphate is a white powdery compound known for its chemical properties, including being slowly soluble in acids and insoluble in water. It is a versatile material with various applications across different industries due to its unique characteristics.
Uses
Used in Glass Industry:
Barium metaphosphate is used as a flame retardant in the glass industry for enhancing the safety and performance of glass products. Its flame retardant properties help to slow down the spread of fire, making it a valuable additive in the production of certain types of glasses.
Used in Porcelain Industry:
In the porcelain industry, barium metaphosphate is utilized as an additive to improve the quality and durability of porcelain products. Its chemical properties contribute to the overall strength and resistance of the finished porcelain items, making them more resistant to wear and tear.
Used in Enamel Industry:
Barium metaphosphate is employed as a key component in the production of enamels, which are used to coat various surfaces for added protection and aesthetic appeal. Its properties help to enhance the durability and resistance of enamel coatings, making them more effective in their intended applications.
Used in Phosphors Applications:
Barium metaphosphate also finds use in the field of phosphors, where it is utilized for its unique luminescent properties. These properties make it a valuable component in the creation of materials that emit light when exposed to certain stimuli, such as ultraviolet light or electron beams. This application is particularly relevant in the development of advanced lighting technologies and display systems.
Preparation
Barium metaphosphate can be prepared by the solidstate
reaction of metaphosphoric acid and the
hydroxide, oxide or carbonate of barium:
BaCO3 + HPO3 + heat ? Ba(PO3)2 +H2O + CO2
The best temperature to use is about 700°C. It has the
CAS number of 13762-83-9 and the molecular weight of
295.2709 g/mol. If diammonium phosphate is used
instead of solid metaphosphoric acid, the product is
not pure. Colored glasses are obtained caused by the
reduction of P-atoms in the phosphate anion by
hydrogen released from NH3 to form colloidal dispersions
of P4 which produce various colors in the glass.
b-Ba(PO3)2 is the final product. This compound can
also be prepared by the aqueous reactions:
NaPO3 (aq) + BaCl2 (aq) ? Ba(PO3)2 (solid) + NaCl (aq)
or
Ba(OH)2 (solid) + 2HPO3 (aq) ? Ba(PO3)2 (solid)
+ 2H2O
The dissolution and reaction involving HPO3 are
slow and should be carried out in a hot solution. Evaporation
at a low temperature (<15°C) serves to form the
crystals. The product involves several hydrates depending
upon the conditions of precipitation. Anhydrous
barium metaphosphate is a white porous powder or
granular material that is insoluble in water.
Check Digit Verification of cas no
The CAS Registry Mumber 13762-83-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,6 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 13762-83:
(7*1)+(6*3)+(5*7)+(4*6)+(3*2)+(2*8)+(1*3)=109
109 % 10 = 9
So 13762-83-9 is a valid CAS Registry Number.
