Development of metakaolin and geopolymer

Usually, proppants are made by the sintering of high-grade bauxite or kaolin. High-grade bauxite is used because of its high mechanical strength after heat treatment. Such property is crucial for proppants at great depths due to the closure stress in the hydrocarbon region may exceed 8000 psi 5.

The sintering-strengthening effect of the additions of the highly ferrous bauxite (with Fe 2 O 3 content of 20-25 % in the calcined state) in the compositions with refractory clays was established. It was found that in the temperature range 1350-1500°C the additions of bauxite in amounts of 10-40% have a fluxing effect due to the iron oxide introduced with bauxite in compositions with clay.
