Crystal Structure

The crystal structure describes the arrangement pattern of atoms, ions, or molecules in a crystal. According to symmetry, crystals can be divided into seven major crystal systems, each with unique geometric features. These features have a decisive impact on the performance of materials, therefore understanding the crystal structure is crucial for designing and preparing crystal materials with specific functions.

The classification of crystal structures is based on the symmetry of crystals and the geometric properties of unit cells. Based on these characteristics, crystals can be divided into seven major crystal systems, which are: 1. Cubic Crystal System: green fluorite; 2. Tetragonal Crystal System: cassiterite; 3. Trigonal Crystal System: Calcite; 4. Hexagonal Crystal System: Hailanbao; 5. Orthorhombic crystal system: (0rthorhobic Crystal System): antimonite; 6. Monoclinic Crystal System: Epidote; 7. Triclini crystal system.

Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.
