The role of the chemical composition of monetite
on the synthesis and properties of a-tricalcium phosphate.
By contrast, acidic calcium phosphates, dicalcium phosphate anhydrous (CaHP[O.sub.4] , DCPA, Monetite
) and dicalcium phosphate dehydrate (CaHP[O.sub.4]-[H.sub.2]O, DCPD, Brushite), are more degradable at physiologic pH than HA and will form a [Ca.sup.2+] and P[O.sub.4.sup.3-] supersaturated zone at the interface of implant and bone that may induce osteoblastic differentiation .
Briefly, a stoichiometric mixture of Mg-free calcium carbonate (CaC[O.sub.3]) and Mg-free monetite
(CaHP[O.sub.4]) was calcined at 1300[degrees]C and milled to achieve a granulometric distribution of 1.33 to 10 [micro]m and a mean particle size of 4.93 [micro]m.
After setting, calcium silicate (rankinite, Ca3Si2O7), tricalcium silicate oxide ([Ca.sub.3](Si[O.sub.4])O; card number: 01-070-1846), calcium hydroxide phosphate (monetite
, CaHP[O.sub.4]; card number: 01-070-0359), calcium sulfate (Ca[S.sub.3][O.sub.10]; card number: 00-021-0166), and calcium phosphate (catena Ca(P[O.sub.3])2, card number: 01-079-0700 and Whitelockite [beta]-TCP, [Ca.sub.3][(P[O.sub.4]).sub.2]; card number: 00-055-0898) phases were detected (Figure 2(b)).
The reaction for obtaining the [beta]-TCP powder consisted of a mixture of calcium carbonate (CaC[O.sub.3] --Synth, Brazil) and monetite
(CaHP[O.sub.4]--Synth, Brazil) at a molar ratio of 1:2 (Equation 1).

Commercially available calcium sulfate hemihydrate (CSH) powders were mixed with anhydrous calcium hydrogen phosphate (monetite
) in order to develop a novel resorbable orthopedic cement.

It is also noted that a weak peak of monetite
is recorded at the highest sintering temperature (1300[degrees]C).
