7758-87-4 Usage

Description

Calcium Phosphate is the calcium salt of phosphoric acid with widely used applications. It occur abundantly in nature in several forms and are the principal minerals for the production of phosphate fertilizers and for a range of phosphorus compounds. For example, the tribasic variety (precipitated calcium phosphate), Ca3(PO4)2, is the principal inorganic constituent of bone ash. The acid salt Ca(H2PO4)2, produced by treating mineral phosphates with sulfuric acid, is employed as a plant food and stabilizer for plastics. It is a natural constituent of mammals, and it is a component of bone replacement transplants in much higher amounts with no toxicological problems. Calcium phosphates are the largest group of artificial bone graft substitutes. This is mainly due to their close resemblance to the mineral components of bone. This Product can be used as a countermeasure for exposure to strontium and radium radionuclides. Upon oral uptake, calcium phosphate competes for and blocks the absorption of radium (Ra-226) and strontium (Sr-90) in the gastrointestinal (GI) tract.

Chemical Properties

Different sources of media describe the Chemical Properties of 7758-87-4 differently. You can refer to the following data:
1. White or almost white powder.
2. Tricalcium phosphate is white solid, insoluble in water; reactive with silicon oxide and carbon at electric furnace temperature yielding phosphorus vapor; reactive with H2SO4 to form, according to the proportions used, phosphoric acid, or dicalcium hydrogen phosphate, CaHPO4, white solid, insoluble; or calcium dihydrogen phosphate, Ca(H2PO4)2·H2O, white solid, soluble. pKsp = 28.70.

Physical properties

White amorphous powder; refractive index 1.63; density 3.14 g/cm3; melts at 1,670°C; insoluble in water; KSP 1.0x10-25; soluble in acids.

Occurrence

Tribasic calcium phosphate occurs in nature as minerals, oxydapatite, whitlockite, voelicherite, apatite, phosphorite. It has many industrial applica tions. Some are similar to the monobasic and dibasic salts. It is used in fertil izers, dental products, ceramics and polishing powder. Some other important applications are in plastics as a stabilizer; as an anticaking agent; as a nutri ent supplement in cattle food; for clarifying sugar syrup; as a mordant in dye ing textiles; and as a buffer to control pH.

Uses

Different sources of media describe the Uses of 7758-87-4 differently. You can refer to the following data:
1. Calcium Phosphate is a compound existing in several forms which include the monobasic, dibasic, and tribasic forms of calcium phos- phate. as calcium phosphate monobasic, also termed monocalcium phosphate, calcium biphosphate, and acid calcium phosphate, it is used as a leavening agent and acidulant. calcium phosphate diba- sic, also termed dicalcium phosphate dihydrate, is used as a dough conditioner and mineral supplement. calcium phosphate tribasic, also termed tricalcium phosphate and precipitated calcium phos- phate, is used as an anticaking agent, mineral supplement, and con- ditioning agent.
2. Calcium Phosphate is an anticaking agent and calcium source that is a white powder that is almost insoluble in water. It is used as an anticaking agent in table salt and dry vinegar. It is used as a source of calcium and phosphorus in cereals and desserts. It functions as a bleaching agent in flour and in lard, and prevents undesirable coloring and improves stability for frying. It is also termed tribasic calcium phosphate, tricalcium orthophosphate, calcium phosphate tribasic, and precipitated calcium phosphate.
3. manufacture of fertilizers, H3PO4 and P Compounds; manufacture of milk-glass, polishing and dental powders, porcelains, pottery; enameling; clarifying sugar syrups; in animal feeds; as noncaking agent; in the textile industry.
4. Tribasic calcium phosphate occurs in nature as minerals, oxydapatite, whitlockite, voelicherite, apatite, phosphorite. It has many industrial applications. Some are similar to the monobasic and dibasic salts. It is used in fertilizers, dental products, ceramics and polishing powder. Some other important applications are in plastics as a stabilizer; as an anticaking agent; as a nutrient supplement in cattle food; for clarifying sugar syrup; as a mordant in dyeing textiles; and as a buffer to control pH.

Check Digit Verification of cas no

The CAS Registry Mumber 7758-87-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,5 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7758-87:
(6*7)+(5*7)+(4*5)+(3*8)+(2*8)+(1*7)=144
144 % 10 = 4
So 7758-87-4 is a valid CAS Registry Number.
