Quartz

Purity That Powers Innovation

Quartz (SiO2) is one of the most abundant and versatile minerals on Earth, prized for its exceptional purity, high hardness, and thermal & mechanical strength and chemically stable and Inert. Its unique physical and chemical properties make it a critical raw material across a range of high-performance applications in advanced industries.

Key Properties:
  • High Purity: Especially low in iron, titanium, and aluminium – essential for high-tech applications.
  • Hardness: 7 on Mohs scale – offers high resistance to wear and abrasion.
  • Thermal Stability: Performs under extreme temperatures without deformation.
  • Chemical Inertness: Maintains integrity in acidic and corrosive environments.
  • Low Thermal Expansion: Minimises distortion under heat, ideal for precision components.
  • Excellent Optical Clarity: High transmission in UV and visible wavelengths, critical for optics and electronics.


Grades Offered:
  • Grade 1+ (Raw SiO2 > 99.9880%): Ultra-high purity for semiconductor, optical fibre, speciality aviation, space light and premium solar applications.
  • Grade 1 (Raw SiO2 > 99.9750%): High-purity quartz for solar, crucibles, and precision glass applications.
  • Grade 2 (Raw SiO2 > 99.9680%): Industrial-grade quartz suitable for ceramics, foundry, and general-purpose use.

Applications

Crucibles

Used in the production of fused silica crucibles for silicon melting in the semiconductor and solar industries. Quartz offers outstanding thermal shock resistance, low thermal conductivity, and minimal contamination, making it indispensable for ultra-clean environments.

Optical Fibre

Quartz’s high purity and optical transparency are vital for drawing fine, low-attenuation optical fibres. It ensures maximum signal clarity and long-distance transmission in modern communication systems.

Solar Applications

Quartz is integral to photovoltaic manufacturing, especially in the production of quartz crucibles for monocrystalline silicon growth. Its durability supports high-temperature operations while maintaining purity in silicon production.

Semiconductors

Quartz is used in wafer carriers, process tubes, and other fabrication equipment. Its non-reactive, highly stable nature ensures clean processing conditions, essential for advanced microelectronics.
