Benefits of technology

This patented modification describes how certain types of clay mineral called Montmontillonite or Layered Structure (LST) were treated by adding an alkali metal salt like potassium citrate into it for better processing performance. By breaking up this material and create new layers that improve its ability to absorb water from surrounding rocks while still maintaining their original shape when compressed during manufacture, they could be useful in making stronger brick products without relying on expensive chemical agents such as urethanes or epoxy resins. Additionally, these modifications enhance the interaction between different components within the composition, increasing both tensile strength and durability against environmental factors such as temperature changes over time. Overall, this technology allows us to produce various sinterable ceramics made through modifying the compositions' constituents.

Problems solved by technology

The technical issue addressed by this patented research relates how improving the durability or lifespan of buildings made from brick materials can help prevent damage caused by severe environmental conditions such as salt water spray on them over time.
