Alkaline earth stannate

Although many alkali and alkaline earth stannate complexes have been structurally characterized, there are only a few reports of stannyl compounds containing true metal-Sn... 

Many alkali and alkaline earth stannates have been reported and some have been well characterized. The action of heat upon the salt K2Sn(OH)6 produces the hydrates K2Sn03.H20 and 3K2Sn03.2H20 in addition to the anhydrous salt K2Sn03. 

Other. Insoluble alkaline-earth metal and heavy metal stannates are prepared by the metathetic reaction of a soluble salt of the metal with a soluble alkah—metal stannate. They are used as additives to ceramic dielectric bodies (32). The use of bismuth stannate [12777-45-6] Bi2(Sn02)3 5H20, with barium titanate produces a ceramic capacitor body of uniform dielectric constant over a substantial temperature range (33). Ceramic and dielectric properties of individual stannates are given in Reference 34. Other typical commercially available stannates are barium stannate [12009-18-6] BaSnO calcium stannate [12013 6-6] CaSnO magnesium stannate [12032-29-0], MgSnO and strontium stannate [12143-34-9], SrSnO. ... 

It has been found that compounds of the alkaline earth metals as well as rare earths are suitable for vanadium trapping. Patents relating to the use of titanates of calcium (22), barium (23), and strontium (24) have been issued. Equivalent stannates of calcium and strontium have also been recommended (24,25). Rare earths as separate particles (26) and in the same catalyst particle (27) have been proposed. Naturally occurring minerals such as Sepiolite and Dolomite which are rich in magnesium oxide and calcium oxide have been suggested (28).
