The high-temperature transformation of andalusite (A12SiOs) into 3/2-mullite (3A12Oa2SiO2) and vitreous silica (SiO2)
S U M M A R Y . The high-temperature transformation of andalusite (AI2SiOs) into 3/2-mullite (3AIzO32SiO2) plus vitreous silica (SiO2) has been studied within the temperature interval from 13oo to 16oo ~ by means of X-ray powder and single-crystal techniques and by infrared spectroscopy. Results are interpreted in terms of a topotactic transformation in which (oi I) and (oI i) planes of andalus...
متن کاملSpark Plasma Sintered Hydroxyapatite – Zirconia Composites: Structural and Mechanical Properties
Hydroxyapatite (Ca10(PO4)6(OH)2) (HAp) is a very attractive material for human tissue implantation, beacuse it makes up ~69% of the weight of bone [1]. Unfortunately HAp posses low mechanical properties (strength, fracture toughness), which is a barrier to its applications in load-bearing situations [2]. The mechanical properties of HAp composites, is based on the synthesis of composites and th...
متن کاملThe Comparison of MgO and TiO2 Additives Role on Sintering Behavior and Microstructures of Reaction-Sintered Alumina-Zirconia-Mullite Composite
Alumina-Mullite-Zirconia ceramic composites were prepared by reaction sintering of alumina, zircon mixture and the sintering aids of magnesia and titania at temperatures of 1400 and 1600 C for 2 hours. The development of different phases and microstructures of the composites were analysed to assess the relative influence of the additives on the formation of alumina-zirconia-mullite compos...
متن کاملSuperplastic Flow of Two-Phase Ceramics Containing Rigid lnclusions— Zirconia/Mullite Composites
A continuum theory for non-Newtonian flow of a two-phase composite containing rigid inclusions is presented. I t predicts flow suppression by a factor of (1 V)p, where V is the volume fraction of the rigid inclusion and q depends on the stress exponent and the inclusion shape. Stress concentrations in the rigid inclusion have also been evaluated. As the stress exponent increases, flow suppressi...
متن کاملThe Effect of Microsilica and Aluminum Metal Powder on the Densification Parameters, Mechanical Properties and Microstructure of Alumina–Mullite Ceramic Composites
Microsilica, or silica fume, is an amorphous type of silica mostly collected as byproduct of the silicon and ferrosilicon alloy production. In this work, low shrinkage alumina-mullite ceramic composites were prepared from mixtures of calcined alumina, silica fume and aluminum metal powder and sintered at 1550 o C for 2 hrs. The influence of silica fume and aluminum powder on the densification p...
