Description of Sodium Chloride Crystal Substrates

Sodium Chloride (NaCl) crystal is water-soluble, and it is easily deliquescent. It cannot be chemically polished. NaCl single crystal substrates are commonly used as substrate materials for epitaxial thin film growth. NaCl is hygroscopic by nature and very sensitive to moisture. NaCl crystal substrates must be stored in a desiccator container to avoid hydration.

FAQs

Q1 Why is high purity important in Sodium Chloride Crystal Substrates? High purity is essential for ensuring the optical clarity and structural integrity of NaCl crystal substrates. Impurities can affect optical performance, especially in sensitive applications like spectroscopy, where precision and minimal interference are key.

Q2 What are the benefits of using NaCl Crystal Substrates for thin film deposition? NaCl crystal substrates offer a smooth and flat surface, which is ideal for thin film deposition processes. Their high crystalline quality allows for uniform coating, making them suitable for a wide range of deposition techniques like sputtering, evaporation, and chemical vapor deposition (CVD).

Q3. Can Sodium Chloride Crystal Substrates be used in high-temperature applications? Sodium chloride crystals are generally not suitable for high-temperature applications beyond their melting point (about 801°C). For applications requiring high-temperature resistance, materials like sapphire or quartz may be more appropriate.
