Mica Quartz

Precision Mineral for High-Performance Industries

Mica Quartz is a naturally occurring mineral composite consisting of quartz intergrown with mica flakes. Known for its unique blend of mechanical strength, thermal insulation, and electrical resistance, Mica Quartz is ideal for specialised industrial applications requiring high performance under demanding conditions.

Key Properties:
  • Excellent Insulation: Natural mica content offers high dielectric strength and thermal insulation.
  • Good Hardness: Mohs hardness of ~6.5 ensures mechanical durability.
  • Thermal Stability: Performs reliably under fluctuating high-temperature environments.
  • Chemical Resistance: Inert to most acids and alkalis.
  • Dimensional Stability: Low thermal expansion supports structural integrity at elevated temperatures.


Grades Offered:
  • Raw: SiO2= 85.0-98.0%
  • Mica: 2-15%
  • Feldspar: 0-10%

Applications

Crucibles & Refractories

Mica Quartz is used in the production of high-performance crucibles and refractory bricks where thermal shock resistance and structural integrity are critical. Its layered composition helps buffer against rapid temperature changes.

Electrical & Thermal Insulation

The mica component provides excellent electrical insulation and thermal resistance, making Mica Quartz ideal for components used in transformers, furnace linings, and electronic substrates.

Solar Industry

In solar-grade applications, Mica Quartz is utilised in thermal insulation layers and support structures that must endure intense heat during silicon ingot formation.

Semiconductor & Foundry

Its dimensional stability and purity make it valuable in the manufacturing of moulds, crucibles, and ceramic components for the semiconductor and metal casting industries.
