12143-34-9 Usage
Uses
Used in Material Technology:
Strontium stannate is used as a ceramic material for the preparation of thermally stable capacitors and the fabrication of ceramic boundary layer capacitors due to its good dielectric properties.
Used in Sensor Technology:
Strontium stannate is used as a sensor material for detecting various gases, including CO, NOx, H2, and CO2. In both pure and doped forms, it has been investigated as a potential solid-state sensor material. The detection of gas in BaSnO3 sensors is achieved by measuring the changes in electrical properties such as resistance and conductivity, which are induced by the adsorption of gases on the solid surface. The gas sensitivity of this semiconducting oxide is related to the surface reaction process.
Used in Multifunctional Sensor Preparation:
Strontium stannate is used in combination with BaTiO3 for the preparation of multifunctional temperature-humidity-gas sensors, enhancing their capabilities in detecting various environmental parameters.
Preparation
BaSnO3 powder with a crystallite size of 27.6 nm was prepared through a hydrothermal reaction of a peptized SnO2·xH3O and Ba(OH)3 at 250°C. This was followed by crystallization of this hydrothermal product at 330°C. The peptization of the SnO3·xH3O gel is dependent on the pH value. Through peptization, the mean particle size of SnO3·xH3O in the aqueous solution has been decreased by a factor of 100 to 8 nm. A limited agglomeration in the sol-prepared powder was observed under the microscope. The structure evolution and crystallization behaviors of the solprepared powders were investigated by TG-DTA, IR and XRD. The BaSn(OH)6 phase in the as-prepared powder transforms into an amorphous phase at 260°C, from which the BaSnO3 particles nucleate and grow with an increase in temperature. The single-phase BaSnO3 powder has been obtained at a temperature as low as 330°C. This sol-prepared powder is more sinterable than the gel-prepared powder and can be sintered to a ceramic at 340°C with 90.7% of the theoretic density.
Check Digit Verification of cas no
The CAS Registry Mumber 12143-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,4 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 12143-34:
(7*1)+(6*2)+(5*1)+(4*4)+(3*3)+(2*3)+(1*4)=59
59 % 10 = 9
So 12143-34-9 is a valid CAS Registry Number.
