WEBCalcium oxalate monohydrate (CaC2O4.H2O) is commonly used in ceramic glazes for industrial uses, and is the common component of kidney stones in the human body. Many laboratories and universities will use this material as a standard or calibration material before running other TGA samples.
TGA Measurements on Calcium Oxalate Monohydrate
WEBWhen calcium oxalate monohydrate is heated to 1100°C, three clearly separated mass-loss steps can be detected by means of the thermobalance. Figure 2 shows a comparison of the thermogravimetric results of two measurements on calcium oxalate monohydrate samples.

WEBDecomposition Analysis of Calcium Oxalate using TGA Application Note Background Thermal gravimetric analysis (TGA) is a thermal characterization method that measures the mass of a sample over time as the temperature increases at a determined rate.
Thermal decomposition of calcium oxalate: beyond appearances
WEBNov 9, 2018 · The goal of this study is twofold: to take a fresh look at the decomposition of calcium oxalate and to warn users of thermogravimetric analysis against the hasty interpretation of results obtained.
WEBCalcium oxalate monohydrate (CaC2O4.H2O), also known as whewellite, is a main component in kidney stones and is an industrially useful compound used to make oxalic acid and organic oxalates. CaC2O4.H2O is commonly used as a standard to test TGA performance due to its well-known decomposition steps and products2.

WEBThermogravimetric analysis (TGA), which measures weight changes in a material as the material is heated, provides a convenient method for characterizing the decomposition process in inorganics. For example, calcium oxalate monohydrate (CaC 2 O 4 . H 2 O), a standard material often used to verify TGA performance, exhibits three weight losses with
WEBCalcium oxalate monohydrate is used as a standard substance ith rmal analysis [1, 2]. Investigations revealed that upon both dynamic [1, 3-6] and quasi isothermal-isobaric [2] thermoanalytical experiments the compound loses water, carbon monoxide andfinally carbon dioxide ataround 470, 650 and 920 K, respectively [2].
