Yellow Ochre :
Special Quality of Yellow Ochre Raw Materials for Terracotta Vitrified Tiles.

We would like to introduce as leading associates with Bharath Minerals, poinear of Yellow Ochre from Kadapa (A.P.) which is used as raw materials for "Terra Cotta Vitrified Tiles" . We can furnishing the some of our valuable customers who is using our raw materials.

Physical Properties of Yellow Shale :

  1. Pale yellow coloured shale/Ochre, very easily breaks into chips and powder and has no impure ties what so ever.
  2. In wet condition it shows very good plasticity. Its' water of plasticity will be around 40%.
  3. It is absolutely free from carbonates.
  4. In wet condition ionic concentration is so high which show very good fluidic characteristics. No demand for STPP or any deflocculates.
  5. It has a very good green, dried and fired strength i.e. 15,30 and 400 Kgs/cm 2 respectively.
  6. The yellow shale sinters at a very low temperature. It shows zero porosity 1140 0 C.
  7. It burns red after firing.
  8. It has a very good coefficient of linear thermal expansion and the material can be used any amount in the body composition. At 650 0 C, it shows 6.8X10 6 coefficient of linear thermal expansion.
  9. It contains high alkalis which does not demand any flux like feldspar in the body composition.
  10. This materials after firing develops terracotta colour and therefore it is being used in ceramic vitrified tiles (Vitro terracotta tiles are popular in India and abroad).
