The invention relates to a modified geopolymer and a modified geopolymer composite comprising additive. The additive is preferably an athermanous additive. The modification is with one or more water-soluble compounds, the water-soluble compound is preferably selected from phosphorus compounds, nitrogen compounds, copper compounds, silver compounds, zinc compounds, tin compounds and magnesium compounds. Also, it relates to compositions which contain the modified geopolymer or modified geopolymer composite. The compositions preferably comprise vinyl aromatic polymer and are in the form of a foam.

A boehmite structure includes a plurality of boehmite particles where adjacent boehmite particles are bonded to each other. The boehmite structure has a porosity of 30% or less. A method of producing a boehmite structure includes obtaining a mixture by mixing hydraulic alumina with a solvent including water, and pressurizing and heating the mixture under a condition of a pressure of 10 to 600 MPa and a temperature of 50 to 300° C.

Thermoset ceramic compositions and a method of preparation of such compositions. The compositions are advanced organic/inorganic hybrid composite polymer ceramic alloys. The material combines strength, hardness and high temperature performance of technical ceramics with the strength, ductility, thermal shock resistance, density, and easy processing of the polymer. Consisting of a branched backbone of silicon, and alumina, with highly coordinated Si—O—Si or Al—O—Al bonds, the material undergoes sintering at 7 to 300 centigrade for 2 to 94 hours from water at a pH between 0 to 14, humidity of 0 to 100%, with or without vaporous solvents.
