Red and black volcanic stone granules are natural materials formed from solidified lava after volcanic eruptions. These stones are characterized by their porous structure, rough texture, and rich mineral content, making them versatile for various applications.

Product Specifications:

• Color: Available in both red and black hues.

• Size Options: 1-3mm, 3-6mm, 5-8mm, 8-15mm, 10-20mm, 3-5cm, 5-8cm, 10-20cm, 20-30cm; customizable sizes upon request.

• Density: Approximately 700-800 kg/m³.

• Packaging: Standard packaging includes 25kg woven bags; bulk packaging options are available based on customer requirements.

Key Features:

1. High Porosity: The stones have an average porosity of around 80%, ensuring minimal water resistance and efficient water flow.

2. Large Surface Area: The substantial surface area and high open porosity promote rapid biofilm formation, beneficial for biological filtration processes.

3. Durability: These stones are resistant to weathering, acids, and alkalis, ensuring longevity in various environments.

4. Lightweight: Despite their durability, volcanic stones are relatively lightweight, making them easy to handle and apply in different settings.

Applications:

• Water Treatment: Ideal for use as biofilter media in aquariums, ponds, and wastewater treatment facilities due to their high porosity and surface area.

• Horticulture: Enhances soil aeration and drainage, making them suitable for soil improvement and as a growing medium in hydroponics.

• Landscaping: Their natural aesthetic appeal makes them perfect for garden paths, decorative ground cover, and rock gardens.

• Construction: Used as lightweight aggregate in building materials, providing insulation and fire-resistant properties.

• Barbecue Cooking: Commonly utilized as lava rocks in grills due to their heat retention and distribution capabilities.
