An Inorganic Crystal is a Crystal Structure that is composed of Inorganic Compounds.
- Context:
- It can (typically) be formed by the orderly and repetitive arrangement of atoms, ions, or molecules.
- It can (often) exhibit well-defined geometrical shapes with flat faces and sharp angles.
- It can range from being a Naturally Occurring Inorganic Crystal (such as Mineral Crystals found in nature) to being a Synthetic Inorganic Crystal (such as those created in laboratories).
- It can (typically) possess Physical Crystal Properties such as hardness, cleavage, and optical properties that are used in identification and classification.
- It can (often) be categorized based on its Chemical Composition and Crystal System (such as cubic inorganic crystal, tetragonal, orthorhombic, hexagonal, trigonal, monoclinic, and triclinic).
- It can be utilized in various applications, including Semiconductors, Optoelectronic Devices, Catalysts, and Piezoelectric Materials.
- It can be analyzed and identified using techniques like X-ray Crystallography, Electron Microscopy, and Spectroscopy.

- Example(s):* Example(s):
- Tetragonal Inorganic Crystals, such as:
- Quartz Crystal: Composed of silicon dioxide (SiO2).
- Orthorhombic Inorganic Crystals, such as:
- Barite Crystal: A mineral consisting of barium sulfate.
- Trigonal Inorganic Crystals, such as:
- Calcite Crystal: A carbonate mineral used in various industries.
- Magnetic Inorganic Crystals, such as:
- Hematite Crystal: An iron oxide mineral used as an iron ore, known for its magnetic properties in certain forms.
- Semiconductor Inorganic Crystals, such as:
- Gallium Arsenide (GaAs) Crystal: Used in semiconductor applications.
- Optical Inorganic Crystals, such as:
- Quartz Crystal: Known for its piezoelectric and optical properties.
- …
- Tetragonal Inorganic Crystals, such as:
- Counter-Example(s):
- Organic Crystal, such as Sugar Crystals or Protein Crystals, which are composed of organic compounds.
- Amorphous Solids, like glass, which lack a well-defined crystal structure.
- Liquid Crystals, which exhibit properties between those of conventional liquids and solid crystals.
