摘要：
The influence of nano-silica and zircon additions on the sintering and mechanical properties of in situ formed forsterite fired at 1550 degrees C for 2 h was investigated. The results indicated that, nano-silica improved in situ formed forsterite at the firing temperature, while zircon additions enhanced the sintering of the investigated samples. XRD analysis and SEM examination observed a good crystallinity of in situ formed forsterite with nano-silica and/or zircon additions. Densification parameter (BD similar to 3.22 g/cm(3) and AP similar to 5.82%), cold crushing strength (CCS similar to 285 MPa) and micro-hardness (Hv similar to 660) were enhanced with zircon additions.
