QUINTO HERNANDEZ, A.  and  PINA BARBA, Ma. C.. Caracterización física y química de pastas de cementos óseos con ZrO₂. Rev. mex. fis. [online]. 2003, vol.49, n.2, pp.123-131. ISSN 0035-001X.

Setting times and temperature of sixteen calcium phosphate cements added with ZrO₂ were evaluated. Their behaviors were analyzed to be used like injectable formulations in surgery of bone. Two cements of calcium phosphates enriched with ZrO₂ with the best characteristics in setting times and temperature, were mechanically tested after 1 and 7 days of preparad. Density was determined using a picnometer, chemical composition was determined by X-ray diffraction and the molecular structure was determined by mfrared spectroscopy.

Keywords : Biocement; setting times; injectability; chemical composition; mechanical test; molecular structure.
