“…The use of phosphoric acid as a binder for metal matrix composite fiber preforms has also been reported 3 . Phosphoric acid reacts with the alumina fiber to form an aluminum metaphosphate gel on the fiber surface then converts to the final bonding phase, AlPO 4 , on heating.…”

“…As a well‐known inorganic material, aluminum phosphate (AP) has found many applications in catalysts, 1–3 ceramics, 4 refractories, antifreezers, paints, 5 binders, 6–9 and composites 10–14 . AP exhibits several attractive characteristics such as a relatively low density, high‐temperature chemical inertness, and chemical compatibility with many kinds of metals and ceramics (e.g., silicon carbide, alumina, and silica) over a moderate temperature range.…”

Glass fiber-reinforced aluminum phosphate (AP)/silica composites were prepared by hydrolyzing tetraethylorthosilicate (TEOS) in AP binder. The composites were hot pressed and cured at a temperature range between 1401C and 2001C with Al 2 O 3 as a curing agent. Microstructures of the prepared composites were examined using scanning electron microscopy. Flexural properties of the composites were investigated by a three-point bending test. It was found that the flexural strength of the prepared composites was significantly increased when appropriate concentrations of TEOS were used for hydrolysis. A microstructure study demonstrated that the improvement in flexural strength was due to the formation of an interpenetrating network structure between the two inorganic phases.

The effect of several variables such as molar ratio P 2 O 5 /B 2 O 3 (X), temperature and heating cycle on the strength of chemically bonded SiC materials for grinding wheels fabrication was studied. It was shown that the highest compressive strength (52.4 MPa) could be obtained using an optimal molar ratio X = 4.5 and a multiple step heating cycle up to a sintering temperature of 800 o C. DTA, XRD, SEM and dilatometrical analysis were performed to follow the different stages of the structural development.Keywords: phosphate bonding, strength, grinding tools, SiC, chemical bonding. Sinterizacion de nuevos materiales compuestos de sic aglomerados con fosfatos para la fabricacion de muelas abrasivasSe estudia el efecto de diferentes variables tales como la razón molar P 2 O 5 /B 2 O 3 (X), temperatura y ciclo de calentamieno sobre la resistencia de materiales de SiC aglomerados quimicamente para la fabricación de muelas arasivas. Se ha comprobado que la más alta resistencia a la compresión (52,4MPa) pueda obtenerse usando una razón molar òptima x= 4,5 y un ciclo de calentamiento en múltiples etapas hasta la temperatura de 800º C. Estudios mediante ATD, DRX, MEB y análisis dilatométricos fueron llevados a cabo para seguir las diferentes etapas del desarrollo microestructura.
