WHITE TALC, INDUSTRIAL TALC

IRAN MINERAL TALC 

• Chemistry: Mg₃Si₄O₁₀(OH)₂, Magnesium Silicate Hydroxide
• Class: Silicates
• Subclass: phyllosilicates
• Group: Clays and also The Montmorillonite/Smectite Group.
• Uses: an ornamental and heat, acid and electrically-resistant stone (soapstone) used as counter tops, electrical switchboards, carvings, etc, used as an ingredient in paints, rubber, roofing materials, ceramics and insecticides. Most commonly known as the primary ingredient in talcum powder.

The mineral Iran Talc is a hydrous magnesium silicate mined in Iran for many years. A massive talcose rock is called steatite, and an impure massive variety is known as soapstone. Talc is used commercially because of its fragrance retention, luster, purity, softness, and whiteness. Other commercially important properties of Iran talc are its chemical inertness, high dielectric strength, high thermal conductivity, low electrical conductivity, and oil and grease adsorption. The major markets for talc are ceramics, paint, paper, and plastics.  

Iran Talc is an important industrial mineral. Its resistance to heat, electricity and acids make it an ideal surface for lab counter tops and electrical switchboards. It is also an important filler material for paints, rubber and insecticides. Even with all these uses, most people only know talc as the primary ingredient in talcum powder. Mineral specimens are not very common as it does not form very large crystals. However, it often replaces other minerals on an atom by atom basis and forms what are called pseudomorphs (false shape). The talc takes the form of the mineral it replaces. A specimen of what looks like milky quartz is quite a suprise when it not only has a soapy feel but can be scratched by a fingernail.

- PHYSICAL CHARACTERISTICS:

• Color is green, gray and white to almost silver.
• Luster is dull to pearly or greasy.
• Transparency crystals are translucent and masses are opaque.
• Crystal System is monoclinic; 2/m.
• Cleavage is perfect in one direction, basal.
• Fracture is uneven to lamellar.
• Hardness is 1 (can leave mark on paper)
• Specific Gravity is 2.7 - 2.8 (average)
• Streak is white.
• Other Characteristics: cleavage flakes are slightly flexible but not elastic and talc has a soapy feel to the touch.
• Best Field Indicators softness, color, soapy feel, luster and cleavage.

- Industrial Uses:

Filler in paints, rubber. In cosmetics and as a lubricating dusting powder.
