Cristobalite crystal structure
Cristobalite crystal, molecular model. Cristobalite is a form of quartz (silicon dioxide) that forms at high temperatures, although once formed it persists at lower temperatures in a metastable state. In this model, silicon ions are red and oxygen ions are grey. The unit cell (repeat structure) of the crystal is highlighted by the blue box. This regular cubic arrangement is predominant above around 1400 degrees Celsius, and it reverts to a more disordered arrangement of SiO4 tetrahedra (grey) when cooled below 250 degrees. However the regular cubic form can persist when cooled if the crystal is constrained by its surroundings, as the reordering changes the shape of the crystal

EDITORS COMMENTS
This print showcases the intricate beauty of the Cristobalite crystal structure. The molecular model depicts a form of quartz, specifically silicon dioxide, that emerges at high temperatures and remains in a metastable state even when cooled down. The visual representation highlights the arrangement of red silicon ions and grey oxygen ions within the unit cell, which is enclosed by a striking blue box. Above 1400 degrees Celsius, this regular cubic arrangement dominates the crystal's composition. However, upon cooling below 250 degrees Celsius, it transforms into a more disordered configuration of SiO4 tetrahedra depicted in grey. Interestingly, if constrained by its surroundings during cooling, this regular cubic form can persist despite the reordering that alters its shape. The image not only provides an insight into the structural complexity of cristobalite but also serves as an illustration for various scientific concepts such as chemistry, atoms, compounds, and minerals. It represents how different elements come together to create fascinating structures with unique properties. Displayed through computer artwork techniques with meticulous attention to detail and precision, this photograph from Science Photo Library captures both scientific accuracy and aesthetic appeal. It offers viewers an opportunity to appreciate the wonders hidden within our world at microscopic levels while reminding us of nature's ability to create mesmerizing forms through chemical interactions.
