A butadiene-1,3-styrene copolymer was prepared according to the general method of Example 3, above, from n-BuLi and the Ba salt. The barium salt used was prepared according to Example 1, above, and had not over about 0.01 wt. % N2; it had the empirical formula: Ba[(t-decoxide)0.61...
In its composition aspects, this invention comprises a double oxide of Ba and Co prepared by reacting CoO with BaO or Ba(OH)2 in the presence of steam. When Ba(OH)2 or BaO react with CoO in a Ba/Co mole ratio of 1 or less, a double oxide having the empirical formula BaCoO2.33 ...
As silicon and barium play interstitial roles in the layers of octahedra, although potentially an orthosilicate, the mineral is more akin to an oxide.BARTHOLOMEW, Paul R
As for ionic liquid like oxide-ceramic melt, strongly bonded metal cation-oxygen polyhedra are prominent SRO clusters, which are treated as local structural unit. In BT2 melt, the Ti-O polyhedra instead of the Ba-O polyhedra is assigned as structural unit due to much a stronger chemical bond...

The empirical formula of the compound caging CO 2 (as well as O 2) is expressed by 4 BaO · 12WO 3 · 1 2O 2 · 2CO 2. On further heating, these caged molecules are released when crystallization occurs around 520°C.doi:10.1016/0022-4596(87)90197-6Tetsuichi Kudo...
those based on barium titanate, are prepd. from oxide, carbonate, etc. A part of the starting materials is only added after the reaction of those starting materials forming the main material. These starting materials are reacted separately to give a cpd. which is then added to the already ...
