实施例通过改变应用的组分和施加的热处理对此进行说明。 根据本发明的玻璃陶瓷具有特别是至少5.0·10-6K-1,优选为10.0至20.0·10-6K-1,且特别优选为13.0至18.0·10-6K-1的热膨胀系数CTE(在100至500℃的范围内测得的)。该CTE是根据ISO 6872(2008)测定的。 根据本发明的玻璃陶瓷的特征在于
随着沉积气体流速的增加，英思特观察到从拉伸应力到压缩应力的转变。沉积速率随着流速的增加而增加，这可以通过更多的试剂到达衬底表面和沉积不受反应限制来解释，由于沉积温度在所有样品中保持不变，因此可以消除由热膨胀系数(CTE)不匹配引起的残余应力。英思特研究了内在应力如何影响悬二氧化硅桥(以下简称“桥”)的制作...
0, 1, 3, 5, 8, 10 and 15 wt% prepared using the sol–gel technique was obtained in the temperature range of 120 to 200 °C using the newly improved CCD method and the differential coefficient thermal expansion (CTE) can be deduced by Δ L/ L 0 temperature relation. The CTE of ...
核壳结构的SiC@SiO2纳米线制备环氧/SiC@SiO2复合材料过程 使用像SiC纳米线(NWs)这样的新型具有优异物理性能的填充物,可以获得具有非常低的CTE,不匹配硅性质的新型电子封装复合材料。下文介绍核壳结构的SiC@SiO2纳米线制备环氧/SiC@SiO2复合材料过程。 1)制备核壳SiC@SiO2 NWs,将所需数量的SiC,NWs添加到石墨坩埚,放...
The apparent densities, coefficients of thermal expansion (CTE), and softening points of the La2O3–Al2O3–SiO2–B2O3 glasses prepared in this study ranged respectively from 3.24 to 4.54 g/cm3, 4.1 to 8.1 ppm/°C, and 912 to 937 °C, depending on the glass composition. The CTE value...
