Dental Materials Journal, 2003 Part I of this study presented a hypothesis that the thermal expansion of gypsum-bonded investment should become higher under heating conditions favorable for the formation of ahemihydrate. The present study aimed at proving this hypothesis by simulating the rapid heating condition employed in the quick casting technique.

Dental Materials Journal, 2004 A simultaneous differential thermal analysis and thermogravimetry method previously established was used to estimate the composition of gypsum-bonded investment marketed for the quick casting technique. Three commercial investments of this type were heated to 700 degrees C at 10 degrees C/min and the hemihydrate content was estimated by the mass ...

Dense hydroxy apatite ceramics through gel casting technique
, 1996 A simple gel casting process is described for the preparation of uniform green HAP (hydroxy apatite) ceramic bodies. Such green compacts were observed to sinter more uniformly compared to the compacts derived by the dry pressing technique.
