Vermiculite is a premium natural inorganic silicate mineral, meticulously processed through granite hydration to create a mica-like structure. Renowned for its exceptional versatility, our vermiculite is available in various forms, including raw flakes and expanded vermiculite, and comes in professional grades such as golden, silver, and milky white to suit diverse industrial requirements.
Through a precision high-temperature calcination process, the material undergoes rapid thermal expansion—increasing its volume by 6 to 20 times. This results in a lightweight, layered structure with superior thermal and electrical insulation properties, capable of withstanding extreme temperatures up to 1100°C, making it an indispensable asset for modern industrial and agricultural applications.

Frequently Asked Questions
Q: What is the difference between vermiculite flakes and expanded vermiculite?
Vermiculite flakes are the raw mineral form, while expanded vermiculite has been subjected to high-temperature calcination, causing it to expand 6 to 20 times in volume, significantly increasing its insulation properties.
Q: How is vermiculite used in the metallurgy industry?
In metallurgy, it is primarily used as a steel frame coating material, a metallurgical slag removal agent, and as a key component in refractory materials due to its high temperature resistance.
Q: Can vermiculite be used for agricultural purposes?
Yes, it is widely used in horticulture and forestry as a soil conditioner, wetting agent, and seed preservative to enhance plant growth and water retention.
Q: What are the typical shipping ports for your vermiculite products?
Our products are primarily shipped from Xingang Port or Qingdao Port, China, ensuring efficient logistics for international customers.
Q: Is vermiculite safe for use in construction fireproofing?
Absolutely. Because it can withstand temperatures up to 1100°C, it is an ideal material for fireproof boards, fireproof mortar, and fireproof bricks.
Q: What chemical compositions are most prevalent in your vermiculite?
Our vermiculite typically consists of 40-50% SiO2 and 20-30% Al2O3, along with trace amounts of CaO, MgO, and Fe2O3, ensuring industrial-grade performance.
