ProductDescription : Below are some special features of this material：

Annealed Feature: Gray tin has a crystal structure that is stable at low temperatures, specifically below 13.2°C.This feature is significant in the context of phase changes and material stability, particularly in applications where temperature fluctuations occur.

Coefficient of Expansion: The expansion coefficient of gray tin is an important feature that affects its use in environments subject to thermal cycling. Understanding this property is crucial for incorporating gray tin into systems where dimensional stability over temperature changes is necessary.

Electrical Conductivity: Though not as high as other allotropes of tin, gray tin still possesses a certain level of electrical conductivity. This allows for potential use in niche conductive applications, where its other physical properties are also favorable.

Crystal Structure: Gray tin has a diamond cubic crystal structure, similar to diamond and silicon. This structure accounts for some of its unique characteristics and provides opportunities for use in semiconductor applications where this particular geometry can be beneficial.

Fragility: Due to its brittle nature, gray tin can't be used in structural applications where mechanical strength is crucial. Instead, this feature is considered in research and academic settings for understanding phase transitions and material properties.

Material Trans formation: Gray tin can transform into white tin at temperatures above 13.2°C, a feature that can be utilized to study phase transitions and metastability in materials science.

Low Thermal Conductivity: Gray tin exhibits low thermal conductivity, which can be beneficial for thermal insulation applications in specific environments, contrasting its use from the more conductive white tin variant.

Density Differences: The density of gray tin (5.75 g/cm°) is lower than that of white tin (7.28 g/cm°), impacting its selection for applications where weight considerations are critical.

Temperature Sensitivity: Being temperature-sensitive, gray tin is largely studied in the context of solid-state physics to observe changes in properties like lattice parameters and atomic interaction at low temperatures.

Metamorphosis Impact: Known as "tin pest," the transformation from gray to white tin can lead to structural degradation. This phenomenon is particularly important in contexts where tin is used in long-term storage or harsh environmental conditions.
