1306-06-5 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 1306-06-5 differently. You can refer to the following data:
1. Tricalcium phosphate is an odorless and tasteless powder that is stable in air. Tribasic calcium phosphate consists of a
variable mixture of calcium phosphates having the approximate composition of 10CaO·3P2O5·H2O.
2. white powder
Occurrence
Occurs in nature as the minerals: oxydapatit, voelicherite, whitlockite.
Uses
Different sources of media describe the Uses of 1306-06-5 differently. You can refer to the following data:
1. Hydroxyapatite and tricalcium phosphate are bioactive ceramic materials and they find applications as bone grafts, fillers and coating material for metal implants.
2. Prosthetic aid (artificial bone and teeth).
3. In the 1970s, it was found that sintered calcium
hydroxyapatite, (Ca10(PO4)6(OH)2 (abbreviated as
CaHap), possessed excellent biocompatibility and nontoxicity
with femur and mandible bones. Since then,
CaHap has been used as a biomaterial for artificial teeth
and bones and as a filler for cements and polymers.
Today, bone fillers made of CaHap are widely used in
the medical and dental fields. In the 1980s, it was found
that sintered CaHap has a good compatibility with skin
tissues. Hence, percutaneous devices based on CaHap
have been developed and applications have included
continuous ambulatory peritoneal dialysis and intravenous
hyperalimentation systems, blood pressure
measurement and blood access for nutrition. Recently,
many researchers have studied the chemistry of apatites,
particularly CaHap, and have found various applications,
such as artificial teeth and bones, ion exchangers,
adsorbents for chromatography to separate proteins and
enzymes, catalysts, ionic conductors, temperature and
gas sensors, etc.
Preparation
The technical product is also known as “bone ash.” Commercial preparation from phosphate rock.
Definition
The major constituent of bone and tooth mineral. It is finely divided, crystalline, nonstoichiometric material rich in surface ions (carbonate, magnesium, citrate), which are readily replaced by fluoride ion, thus affording protection to the teeth.
Brand name
Alveograf (Sterling Winthrop); Periograf (Sterling Winthrop).
General Description
Bone and tooth implant materials have been prepared from polycrystalline hydroxyapatite. The compressive, flexural, torsional and dynamic torsional strengths of polycrystalline hydroxyapatite were investigated. Electrophoretic deposition of hydroxyapatite on to flat titanium plate material has been studied.
Flammability and Explosibility
Notclassified
Pharmaceutical Applications
Modified hydroxylapatite, also frequently called hydroxyapatite and better known as bone mineral, makes
up ～50% of our bones. Hydroxylapatite is a natural form of the mineral calcium apatite, whose formula is usually denoted as Ca10(PO4)6(OH)2. Modifications of hydroxylapatite can also be found in the teeth, and a
chemically identical substance is often used as filler for replacement of bones, and so on. Nevertheless, despite
similar or identical chemical compositions, the response of the body to these compounds can be quite different.
Check Digit Verification of cas no
The CAS Registry Mumber 1306-06-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,0 and 6 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1306-06:
(6*1)+(5*3)+(4*0)+(3*6)+(2*0)+(1*6)=45
45 % 10 = 5
So 1306-06-5 is a valid CAS Registry Number.
