estimation of sulphate as titanium dioxide

The majority of the world's production of titanium dioxide goes into the manufacturing of paints, coatings, plastics, paper, and ink. As a pigment, it boasts high refractive index properties that provide exceptional opacity and brightness, making it ideal for enhancing the durability and appearance of products. Moreover, titanium dioxide's stability and ability to withstand high temperatures mean it can be used in exterior paints designed to resist fading caused by sunlight exposure.

  • Natural barite and anthracite containing more than 95% barium sulfate are mixed and fed at a ratio of 3:1 (mass). After being crushed to a diameter of less than 2cm, it enters the reduction furnace. The furnace temperature is controlled to be 1000-1200°C in the front section and 500-500 in the back section. 600°C, the reduction furnace rotates at a speed of 80 seconds per revolution, and the reaction conversion rate is 80% to 90%.
