Physical Properties and High-Temperature Resistance of Granite/Marble
As a natural hard stone, Granite/Marble boasts extremely high density and hardness, enabling it to maintain excellent stability in high-temperature environments. Additionally, the mineral composition of Granite/Marble is primarily composed of high-temperature resistant minerals such as quartz, feldspar, and mica, which are not prone to decomposition or phase transformation at high temperatures, thus ensuring the stability of Granite/Marble's overall structure. Scientists have found in experiments that when subjected to high temperatures (e.g., 500-700°C), although Granite/Marble may exhibit phenomena such as increased volume, reduced mass, and decreased elastic modulus, its overall structure remains significantly intact. This is mainly attributed to the tight arrangement and strong binding force between mineral particles inside Granite/Marble, allowing it to maintain good mechanical properties and structural stability at high temperatures.
Application Advantages of High-Temperature Resistance
- Strong Stability: In high-temperature environments, precision Granite/Marble components can maintain excellent dimensional and shape stability, which is particularly crucial for high-precision measurement and machining.
- Superior Deformation Resistance: Due to Granite/Marble's extremely low linear expansion coefficient, it is not easily deformed under high temperatures, ensuring the accuracy and performance of components.
- Excellent Corrosion Resistance: Granite/Marble demonstrates good corrosion resistance to various chemical substances. Even when exposed to corrosive media at high temperatures, it can maintain stable performance.
Long Service Life: With outstanding high-temperature resistance, precision Granite/Marble components can sustain stable performance and longevity in high-temperature environments, reducing replacement and maintenance costs.
