Way to Develop your Skills


The Silicon Chip which has emerged as a boon to the Electronic Industry, prompted us in setting up an exclusive factory for manufacturing High Purity Silica Power for catering distinctly to Global semi-conductor market. Chettinad Morimua Semiconductor Material Private Limited was established in 1991, started its manufacturing activity in 1993. Plant is located at 25kms from Chennai, India. It is a 100% Export Oriented Unit, equipped with dedicated manufacturing lines having the latest Japanese Technology to produce High Purity Silica Powder exceptionally for the Electronic Industry.

We Manufacture
  • Silica
  • Fused Silica
  • Purity Quartz Grits

  • Silica

    The company sources the quartz material from its own resources of more than 90 mines with profuse reserves and also from approved private mine owners which would last for more than two decades, spread all over Tamil Nadu and Andhra Pradesh to comply with the production demand / capacity at any point time
