For example, there are numerous similarities between Project Ai and Project Bi, and they both have phase Preparation, a node named as Raw Material Purchase is placed at the first position in Preparation, based on description in 3.1, the POSITION of Ai’s node Raw Material Purchase is defined as < Ai, Preparation, Raw Material Purchase >, and the POSITION of Bi’s node Raw Material Purchase is defined as < Bi, Preparation, Raw Material Purchase >, we can see that even these two nodes have two factors in common, synchronizer can still distinguish them and to store their produced data in the right position in the database.

However, due to the highly covalent bond characteristics, it is difficult to sinter these materials to full density.
In LPS-SiC materials, typically 5-15 mass% of the Al2O3-Y2O3 additive system is commonly used [1-29,77-79,81,82].

Introduction Lanthanum Cobaltites doped with alkali earth elements (Ca, Sr, Ba) exhibit unique properties and are considered as promising materials for numerous applications such as catalysts for various oxidation-reduction reactions, oxygen permeable membranes or electrodes for different electrochemical devices such as solid oxide fuel cells [1].
Lately, strontium-doped lanthanum cobaltites have been proposed as a cathode material in intermediate temperature SOFCs, due to their high electronic conductivity at intermediate operating temperatures [2,3].
Several wet chemical synthesis techniques have been applied, instead of solid state reactions, for the synthesis of lanthanum cobaltites of high purity and controlled microstructure as the actual composition and the properties of these materials strongly depend on the preparation method. [4, 5] Moreover, using fine particles is regarded as a promising way to improve the homogeneity and sinterability of the powders and achieve the desirable properties.
