About Semi Granular Quartz

Semi-granular quartz is a finely textured form of quartz with moderate granularity, featuring a mix of crystalline and granular structures. Composed primarily of silicon dioxide, it's prized for its strength, durability, and low thermal expansion. This quartz is processed through crushing and refining to achieve its characteristic semi-granular texture. It's commonly used in the production of glass, ceramics, and construction materials, offering improved resistance to heat and wear. Industries such as manufacturing, construction, and electronics benefit from semi-granular quartz due to its versatility, adding both structural integrity and aesthetic appeal to various products.

Key Features & Composition

Made from high-purity quartz, this semi-granular material contains more than 98% silicon dioxide and displays excellent chemical and thermal stability. With a Mohs hardness of 7 and low water absorption (<1%), it meets stringent industrial standards and ensures long-lasting performance in demanding settings.

Versatile Industrial Applications

This quartz is extensively utilized as an industrial raw material for manufacturing refractories, ceramics, glass, and also for water filtration. Its low porosity and high strength enable reliable service in environments where structural integrity, heat resistance, and chemical purity are critical.

Packaging and Delivery Options

To maintain quality, the semi granular quartz is packaged in robust HDPE and jumbo bags. These packaging methods provide secure storage and transport, ensuring the quartz remains free from contamination and moisture, and reaches customers in optimal condition.

FAQ's of Semi Granular Quartz:

Q: How is semi granular quartz typically used in industrial applications?

A: Semi granular quartz is commonly employed as a raw material in refractory manufacturing, ceramics, glass production, and water filtration due to its chemical purity, high heat resistance, and structural stability.

Q: What are the benefits of choosing this type of quartz over other grades?

A: This quartz offers a high SiO2 content (>98%), excellent heat resistance with a melting point of 1710C, low impurities, and minimal moisture, making it ideal for high-performance industrial and refractory usage.

Q: Where does packaging take place and how does it ensure product quality?

A: Packaging is done using HDPE and jumbo bags at manufacturing or export facilities in India. These bags protect the quartz from moisture and contamination during transit and storage, preserving its quality for end users.

Q: What steps are involved in the production process of semi granular quartz?

A: The process typically involves crushing and screening raw quartz to achieve the specified grain size (0.1-3 mm), followed by washing, drying, and thorough quality testing to ensure compliance with physical and chemical specifications.

Q: When is this quartz material preferred in refractory processes?

A: It is preferred when high refractoriness, chemical stability, and mechanical strength are required, such as in furnace linings or other applications operating above 1700C with exposure to harsh conditions.

Q: What advantages does the low acid solubility and minimal loss on ignition provide?

A: Low acid solubility (max 2%) and minor loss on ignition (<0.5%) signify high chemical stability, reducing risks of unwanted reactions during industrial processes and ensuring material reliability and purity.
