Aluminum titanate (Al2TiO5) is
characterized by a low coefficient of thermal
expansion, low modulus of elasticity, and low
mechanical strength. These characteristics are
mainly caused by the anisotropy of thermal
expansion within the tialite crystals leading to
localized internal stresses and microcracking
during cooling from sintering temperature.3
Pure tialite tends to decompose to corundum
and rutile in the temperature range between
approx. 900 °C and 1280 °C. The
decomposition rate depends on temperature,
dwell time, heating rate, phase purity, grain
size, and atmosphere.4 The thermal stability of
metastable Al2TiO5 can be improved by
suitable additives such as MgO which leads to
the formation of Al2TiO5-MgTi2O5 solid
solution during sintering.5

Aluminum titanate (Al2TiO5) is characterized by a low coefficient of thermal expansion, low modulus of elasticity, and low mechanical strength.
鈦酸鋁的熱擴(kuò)散系數(shù)，彈性模量以及力學(xué)強(qiáng)度都比較小。
These characteristics are mainly caused by the anisotropy of thermal expansion within the tialite crystals leading to localized internal stresses and microcracking during cooling from sintering temperature.3
這是因?yàn)殁佀徜X晶體的熱擴(kuò)散是各項(xiàng)異性的，使得在從燒結(jié)溫度冷卻的過(guò)程中，晶體內(nèi)部的應(yīng)力集中形成微裂紋。
Pure tialite tends to decompose to corundum and rutile in the temperature range between approx. 900 °C and 1280 °C.
純的鈦酸鋁在900到1280攝氏度的范圍內(nèi)容易分解成剛玉（氧化鋁）跟金紅石（氧化鈦）。
The decomposition rate depends on temperature, dwell time, heating rate, phase purity, grain size, and atmosphere.

The thermal stability of metastable Al2TiO5 can be improved by suitable additives such as MgO which leads to the formation of Al2TiO5-MgTi2O5 solid solution during sintering.
我們可以通過(guò)在鈦酸鋁中摻入氧化鎂提高其熱穩(wěn)定性。這主要是由于在燒結(jié)過(guò)程中由于氧化鎂的摻入形成了鈦酸鋁-鈦酸鎂的固溶體。
