Research Progress of Magnesium Stabilized Aluminum Titanate and New Application of It in Pigment

Abstract

Aluminum titanate has been widely used in low expansion applications and its thermal stability has been a hot topic. The stability of aluminium titanate research for improving product quality, and expanding its application field is of great significance. Aluminum titanate as glass melt erosion resistance and high temperature resistant, can be applied to high temperature pigment base. The medium temperature stability of aluminum titanate can be improved by ion doping, and magnesium stability of aluminum titanate has been widely studied. Therefore aluminium titanate is expected to become an ideal high temperature ceramic base material. In this paper, the preparation technology of magnesium-stabilized aluminum titanate powder was reviewed, and the preparation of magnesium-stabilized aluminum titanate powder by non-hydrolyzed sol-gel was mainly introduced.

Porous alumina‐based ceramics with very low thermal conductivity prepared by the starch consolidation route

“…The values predicted by each of these models are given in Table 5, calculated using the data of Table 4, where the thermal conductivities of alumina, aluminum titanate, and air were taken as 33, 1.5, and 0.026 W/m.K, respectively. 5,19,49 As for the Maxwell-Eucken model, Equation ( 7) is adopted from Wang et al 47…”

“…In the present work, $${v}_1$$ = (1 − P)$$\ {v}_a$$, $${v}_2\ $$= (1 − P)(1 − $${v}_a$$) and $${v}_3$$ = P, with $${v}_a$$ being the volume fraction of alumina in the Al 2 O 3 –Al 2 TiO 5 system (expression (3) for $${V}_3$$, Tables 2 and 4). The values predicted by each of these models are given in Table 5, calculated using the data of Table 4, where the thermal conductivities of alumina, aluminum titanate, and air were taken as 33, 1.5, and 0.026 W/m.K, respectively 5,19,49 …”
