Volcanic stone is a kind of porous silicate mineral formed by volcanic eruption, cooling and solidification. As a natural functional material widely used in building materials, gardening, water treatment, coatings and industrial fields, it has the core advantages of environmental protection, porosity, weather resistance, stability and high cost-performance. Main types include: red volcanic stone, black volcanic stone, gray volcanic stone.

1. Meticulous craftsmanship: Two production paths ensure controllable and traceable quality

（1）Natural mineral processing

Purified and processed from natural volcanic ore through crushing, screening, cleaning and drying. It retains natural porous structure and mineral activity, low cost, suitable for general scenarios with high costperformance requirements.

（2）High-temperature activation and modification

Adopting precise processes such as high-temperature roasting, surface activation, impurity removal and grading. Raw materials can utilize mining and processing scraps to realize resource recycling, in line with green production trends. Modified products feature high porosity, uniform particle size, stable structure and strong adsorption capacity, meeting the stringent requirements of high-end water treatment, functional coatings and food-contact filtering materials.

1. Core Features: Six Major Advantages Underpin “Abundant Value”

（1）Environmentally friendly and non-toxic, compliant and worry-free

Free of heavy metals and harmful substances, complies with EU REACH, RoHS and Chinese national standards. Non-radioactive, non-polluting, safe for plants, aquatic organisms and human contact, suitable for ecological engineering, water purification and indoor building materials.

（2）Weather-resistant and lightfast, long-lasting and stable

Excellent UV resistance, freezing resistance and aging resistance. No fading, pulverization or breakage after long-term outdoor use, stable in high temperature, rain, humidity and cold environments, making it a “long-life material” for landscape and outdoor engineering.

（3）Acid and alkali resistant and corrosion resistant

Outstanding acid and alkali resistance, compatible with cement, concrete and coating systems; stable to industrial corrosion, no powder or deterioration, widely used in anti-corrosion ground and sewage treatment projects.

（4）Strong porosity and excellent adsorption

Rich internal pores, large specific surface area, strong adsorption of impurities, odor and moisture. Light weight, reducing structural load while achieving filtration and purification effects, with high cost-performance.

（5）Good dispersibility and convenient construction

Hard texture, uniform particle size, easy to mix with cement, asphalt, mortar and coatings. Suitable for paving, filtration, gardening and spraying construction, simple operation and high efficiency.

（6）Batch stability and controllable quality

Formal manufacturers adopt ISO 9001 quality management system, strictly controlling porosity, particle size, color and strength. Each batch is consistent, avoiding losses caused by unstable quality in construction and application.
