water solubility
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Aug 2018
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
no guideline followed
Principles of method if other than guideline:
1.0000 gram +/- 0.005 g reference material was weighed into a 100 mL beaker. 25 mL ultrapure water (≥ 18.2 MΩ) was added. The mixture was stirred on a magnetic stirrer for 15 minutes. The resulting mixture was filtrated over an ashfree filter paper (Whatman Cat No 1440-150).
5 mL of the filtrate was pipetted into a 50 mL volumetric flask. 50 μL yttrium reference standard 1000 ppm was pipetted into the volumetric flask. 2 mL hydrochloric acid 36% was added to the volumetric flask. The volumetric flask was made up to volume with ultrapure water (≥ 18.2 MΩ).
The sample preparation was carried out in duplicate.

element (dissolved fraction)
20 °C
For BCZT the titanate-ion is insoluble; barium-ion is soluble based on the value 906 mg/L Ba2+. BCZT has an higher Ba content than BaTi which leads to a higher Ba2+ solubility in BCZT. Barium (Ba2 +) is leached out from BCZT.

Description of key information

Barium calcium zirconate titanate can be considered as slightly soluble in water.
The titanate-ion is insoluble, the barium-ion is soluble, based on the value 906 mg/l Ba2 +
