Thermally induced switching temperature and spectral transmittance of a novel kind of smart thermotropic material developed by a different mixing proportion of hydroxypropyl methyl cellulose (HPMC), sodium chloride ( NaCl ) and pure water was measured. Radiation transmittance measurements were carried out on a thermotropic double glazing window sample, a double glazing window and a low-E double glazing window. Results show that the thermotropic double-glazed window with optimum mixing proportion of HPMC, NaCl and pure water of 2:10:100 by mass-reduces radiation transmittance at fully turbid state by up to 72% and 32% respectively, compared to the ordinary double-glazed window and low-E double-glazed window which do not have adjustable radiation transmittance; its radiation transmittance changed from transparent state to light scattering state up to 60%, indicating a high performance on switching solar radiation and a great potential for energy efficient windows.

Specimens were prepared using iron-rich magnesia (3~1 mm、≤1 mm) and high purity magnesia (≤0.088 mm) as the main starting materials, adding tabular alumina at different size (3~2、2~1、≤1 mm) and content:3%、6%、9%、12%、15% to discover the influence of tabular alumina on sample performance. Phase composition and microstructure were also analyzed. The results show that specimen with content of 6% of corundum possessed the best comprehensive performance:apparent porosity 17%, bulk density 2.95 g·cm-3, cold crushing strength 74 MPa, refractoriness under load 1700 °C, heat shock resistance of up to 18 times. The formations of magnesium aluminate spinel and hercynite solid solution were enhanced by Fe ion at high temperatures in the iron-rich magnesia-corundum system at the presence of iron oxides, which are able to largely dissolved in periclase.
