| 1 | Thermodynamic study and syntheses of β-SiAlON ceramics显示文摘Based on the thermodynamic study of β-SiAlON and one section of Si-Al-O-N phase diagram for Si/Al=9 at 1773 K, the pure β-SiAlON (Si6-ZAlZOZN8-Z) ceramics with different Z values (viz. 1.4, 1.8, 2.2, 2.6, 3.0) were synthesized at different temperatures using the pressure-less technique. The relationship of the experimental-saturated Z value (the maximum Z value at a constant temperature) with temperature was then discussed. The experimental results indicated that there is a good linear relationship between Z value and temperature, which is Z=_10.76+0.0071T (R=0.9985). The β-SiAlON stability regions at different temperatures were exhibited in a sketch phase diagram of Si3N4-SiO2-Al2O3-AlN system. In addi- tion, the relationship between experimental-saturated Z value and the lattice parameters was also characterized, and the linear regression results a=7.604+0.02872Z and c=2.908+0.02496Z were obtained, respectively. | DONG PengLi WANG XiDong ZHANG Mei GUO Min LI WenChao | 2009 | Science China(Technological Sciences)2009，52，11： | 5 |
| 2 | Conductivity properties of β-SiAlON ceramics显示文摘The thermal diffusivity and heat capacity of β-SiAlON ceramics with different Z values(0.6,1.5,3.0) were measured by laser flash technique and differential scanning calorimetry(DSC),respectively.The thermal conductivity of β-SiAlON was calculated from thermal diffusivity,heat capacity and density and it decreased and then kept almost constant with increasing of temperature.Two different models representing effective thermal conductivity were established and the various parameters of these models were simulated based on the results from the present work.The fitted regression lines were in good agreement with the experimental values. | DONG PengLi WANG XiDong ZHANG Mei SESHADRI Seetharaman | 2012 | Science China(Technological Sciences)2012，55，9： | 1 |
