THERMOGRAVIMETRIC Meaning and
Definition
-
Thermogravimetric, also known as thermogravimetry, is an analytical technique used in science and material characterization. It involves the measurement of the change in mass of a substance as a function of temperature over a controlled heating or cooling program.
The word "thermogravimetric" is derived from the combination of "thermo," which refers to temperature, and "gravimetric," which pertains to the measurement of weight or mass.
In thermogravimetric analysis (TGA), a sample is placed in a controlled environment and is subjected to a programmed increase or decrease in temperature. As the sample is heated or cooled, its mass is continuously monitored by highly sensitive instruments, typically a balance.
The change in mass of the sample is recorded and analyzed to determine various thermal properties. These can include decomposition and reaction kinetics, phase transitions, moisture sorption, thermal stability, and volatile matter content. By studying the mass change over different temperature ranges, valuable information about a material's composition and behavior can be obtained.
Thermogravimetric analysis is widely used in various scientific disciplines, including chemistry, physics, materials science, and engineering. It is particularly valuable in the field of polymer science, where it is used to investigate the thermal stability of polymers, determine their degradation behavior, and study the effects of additives and fillers. Additionally, thermogravimetric analysis finds applications in quality control, product development, and fundamental research.

Etymology of THERMOGRAVIMETRIC
The word "thermogravimetric" is derived from the combination of three Greek roots:
1. "Thermo" - derived from the Greek word "therme" (θερμή), meaning heat or temperature.
2. "Gravi" - derived from the Greek word "gravis" (βάρος), meaning heavy or weight.
3. "Metric" - derived from the Greek word "metron" (μέτρον), meaning measure.
When these roots are combined, "thermogravimetric" literally means "measuring weight changes with temperature". It refers to a technique that measures the change in weight of a substance as it is subjected to varying temperatures, usually in the context of thermal analysis.
