3.The results showed that CeO2 addition obviously prevents the formation of μ-cordierite phase in the glass- ceramics and improves the formation of α-cordierite phase from μ- cordierite.
4.Cordierite-Mullite Board: It is made by high sintering cordierite and mullite together.
5.The present work aims to study the microstructure and properties of La~(3+) and CeO_2modified cordierite ceramics and porous cordierite ceramics.
7.C0.6M0.4ZP coating has good alkali corrosion resistance property and can greatly improve the high temperature alkali corrosion resistance of the cordierite.
9.Chongqing green all Shi Caihang is located township of-Chongqing longevity area the Chinese blue stone but to cross the town.
10.Mineralogical Characteristics of Cordierites in Krn Hy Crd Granulites from the Larsemann Hills, East Antarctica
11.It is found that homogeneous,dense and single-phase C0.6M0.4ZP coating was successfully deposited on cordierite ceramic.
12.The crystallization of the stoichiometric cordierite was studied by using TG-DTA and XRD.
13.STUDY ON STRUCTURE AND IR-RADIATIVE PROPERTIES OF TiC-CORDIERITE MATRIX CONDUCTING CERAMIC
14.The supported water gas shift catalysts have been prepared by impregnation method over cordierite and γ Al 2O 3.By X-ray diffraction(XRD) analysis,it has been found that the supported components on cordierite surface indeed formed perovskite type oxide LaFeO 3.However,there were not any crystal substances such as LaFeO 3 on the surface of γ Al 2O 3 support.
15.The mixed metal oxide catalysts of Cu-Ag-Co-O/ corderite and Cu-Ag-Co-O/ silicon dioxide / corderite were prepared by impregnation method. Effects of temperature and space velocity were investigated. The samples were characterized by BET,XRD,XPS and SEM techniques.
16.A gray, green, or brown mineral similar to mica, formed by chemical alteration of other minerals, such as cordierite.
17.THE CORDIERITE-SILLIMANITE ASSEMBLAGE IN THE ARCHAEAN GRANULITE BELT ON NORTH CHINA PLATFORM AS AN INDICATOR FOR LOWPRESSURE GRANULITE FACIES
18.CeO2 addition decreases the sintering activation energy and lowers the sintering temperature of cordierite glass- ceramics. With 4 %(in mass fraction) of CeO2 added, the lowest temperature for μ- to α-cordierite transformation achieved is about 900 ℃, and the glass-ceramics is in sufficient-densification. But too much CeO2 added will inhibit the sintering and crystallization.
19.The treated cordierite has been studied by BET surface area measurements,XRD,XRF analysis and Boehm titration.
