Diaspore

Diaspore is a mineral composed of aluminum oxide hydroxide (AlO(OH)). It crystallizes in the orthorhombic crystal system and is typically found in bauxite deposits and other aluminum-rich environments formed through the alteration of other minerals like corundum. Known for its relatively high hardness (6.5 to 7 on the Mohs scale) and its ability to show distinct cleavage, diaspore can exhibit different colors, ranging from colorless and white to shades of yellow, brown, and green, often displaying a vitreous to pearly luster. It's an important source of aluminum and is used in the production of refractories and abrasives.

Diaspore meaning with examples

• Geologists discovered significant diaspore deposits during the exploration of a newly formed bauxite mine, revealing its presence in the soil. The diaspore was assessed for its industrial applications, considering its high aluminum content and resistance to heat for various applications.
• The scientist analyzed the chemical composition of the clay-like mineral to identify diaspore through X-ray diffraction methods. The research determined the diaspore's formation process, observing it had crystallized during the late stages of hydrothermal alterations within a granite outcrop.
• The refractories manufacturer relies on diaspore for its high-temperature resistance to fabricate high-quality furnace linings. Due to diaspore's hardness, the manufacturer grinds and processes the mineral to ensure the refractory products have extended durability and life in high-temperature environments.
• Collectors often prize diaspore for its rarity and interesting coloration and physical properties. They search for specimens with beautiful crystal formation, a glassy appearance, or a unique chatoyancy effect for display in mineral collections.
• A mining operation extracts diaspore from a region known for aluminum-rich deposits to be sold to various businesses and is then transported to processing plants. The mining company closely monitors the environmental impacts and the financial value of the mineral diaspore.
