Single Crystal Silicon Cube 12.7mm (0.5 inch), Si Element Sample Cube, Precision-Machined Monocrystalline Silicon Block for STEM Education, Density Experiment, Display & Collection

Discover the unique appearance and material characteristics of silicon with this precision-machined Single Crystal Silicon Cube. Measuring 12.7 × 12.7 × 12.7mm, or approximately 0.5 inch, this compact Si element cube is designed for STEM education, classroom demonstrations, laboratory display, material comparison, and element collections. Made from monocrystalline silicon material, this cube offers a clean metallic-gray surface and a distinctive crystalline appearance that helps students, teachers, collectors, and science enthusiasts better understand one of the most important elements used in modern technology. Silicon is widely known for its role in electronics, semiconductors, solar cells, and advanced materials, making this cube a meaningful addition to any periodic table display or educational collection. The 0.5 inch size is easy to handle, display, and compare with other metal or element cubes. It is especially suitable for density comparison, visual observation, scientific learning, and desktop presentation. Each cube is carefully machined to provide a neat geometric shape and a professional appearance. Please note that silicon is naturally hard and brittle compared with most metals. This product is intended for educational, display, and collection purposes only. Avoid dropping, striking, or applying excessive force to the cube to prevent chipping or damage.
