Lowest Solidifying Temperature, often abbreviated as LST, refers to the lowest temperature at which a substance transitions from a liquid to a solid state. This temperature is a critical property in various fields, including materials science, metallurgy, and chemistry. The LST is influenced by several factors, including the chemical composition of the substance, the presence of impurities, and the rate of cooling.

In metallurgy, the LST is particularly important as it determines the solidification sequence of alloys. For instance, in steel, the LST of the primary phase (usually ferrite or austenite) is crucial for understanding the microstructure and mechanical properties of the final product. The LST can be determined experimentally using techniques such as differential scanning calorimetry (DSC) or thermal analysis.

The concept of LST is also relevant in the study of phase transitions in materials. For example, in the case of polymers, the LST can affect the processing conditions and the final properties of the material. In the field of chemistry, the LST is used to predict the behavior of substances under different temperature conditions.

Understanding the LST is essential for optimizing processes and ensuring the desired properties of materials. It is a fundamental parameter in the design and development of new materials and technologies.
