Advanced lead-free radiation protection materials utilizing modified brine sludge composition and the process thereof

A process for making an advanced lead-free radiation protection material utilizing modified brine sludge composition, the process comprising:

• a. drying of 200 g-800 g of brine sludge in an air oven at 100° C.-110° C. for a period of 1-2 hours to produce a heat-treated brine sludge, followed by simultaneous solid state reaction processing and dry grinding with 20-90 g of tungsten powder and 10 g-60 g metakaolin for a period of 2-4 hours;
• b. after step a, adding and grinding 2 g-8 g potassium hydroxide for a period of 1-2 hrs and further adding and grinding 1 g-4 g potassium silicate for a period of 1-2 hrs to obtain fine homogeneous radiation protection powder of modified brine sludge composition;
• c. after step b, adding and thoroughly blending with 4 ml-16 ml of water and compacting in a steel mold by providing hydraulic pressure in the range of 100-300 kg/cm2 to obtain tiles;
• and
• d. after step c, heating the tiles in a furnace in the temperature range of 900° C.-1100° C. for a period of 1-2 hours to obtain the advanced lead-free radiation protection material.
