莫来石（或莫乃石、Aluminum silicate）指的是一系列由铝硅酸盐组成的矿物统称，值得一提的是SiO2-Al2O3系是陶瓷中最重要的二元系，从1909年公布的第一张莫来石相图，陆续发表了十几张不同的相图，争论的焦点是就是中间相莫来石是稳定化合物还是非稳定化合物 ...

2015年1月5日 · Presented experimental results concern the influence of SiO 2 to Al 2 O 3 ratio on the phase composition and structure of porcelain glazes of the SiO 2 –Al 2 O 3 –CaO–MgO–Na 2 O–K 2 O. Six sets of porcelain glazes designed for firing temperature of 1220–1240 °C were selected for the study.

2020年10月8日 · To study the mechanical properties of Al2O3/SiO2 composites under high-temperature environment and after high-temperature treatment, the tensile strength and fracture behavior of it under high temperatures were investigated, and their flexural strength after heat treatment at various temperatures was also examined.

2023年12月1日 · Al 2 O 3, as a network intermediate and one of the main chemical components of glass, may improve the mechanical strength and thermal stability of glass.

2016年1月1日 · We have developed a new sol–gel route to synthesize Al 2 O 3 –SiO 2 composite aerogel using inexpensive inorganic salt of aluminum. The approach, which is straightforward, inexpensive, and safe, can be employed to produce a monolithic mesoporous material with a high specific surface area, which is heat-treated at high temperatures.

2020年6月24日 · The aim of this study was the synthesis and structural characterization of SiO2–Al2O3 microspheres with SiO2 core and (100 − x)Al2O3·xFe2O3 (x = 0, 5, and 10 mol%) shell. Smooth spherical silica particles of uniform size around 1 μm have been synthesized as core material based on the Stöber method.

2024年10月6日 · 在高温环境下，铝氧化物（Al2O3）与二氧化硅（SiO2）会发生化学反应，生成一种名为mullite的化合物，其化学式为3Al2O3·2SiO2。 这种复合物由于其优异的热稳定性和机械性能，在陶瓷、耐火材料和玻璃制造等多个领域得到广泛应用。

对一步法制备的Al2O3-SiO2气凝胶进行性能测试与表征。测得最终样品中氧化铝含量为1.047%。样品微观结构呈多孔的三维网络结构，内部的二氧化硅为无定形态。高温处理结果表明Al2O3-SiO2气凝胶具有较好的高温稳定性。

1 天前 · In this paper, Al2O3–SiO2 aerogel was compounded with mullite fiber to prepare silicon–aluminum aerogel fiber felt. When the strain value reaches 30%, the compressive strength of the fiber felt with aerogel content of 50.1 wt % reaches 0.21 MPa, and the thermal conductivity of fiber felt decreases from 0.0425 to 0.0322 W/m K when the ...
