Inorganic polymers were known since the 70’s of the 20th century, when mankind was informed by the presence of some pyroxenes, or of some stones like obsidian, all of them are the natural polymers, not as simply as the basic crystal of minerals. Such a polymer is comprised of macro-molecules long of 10.000 times of basic molecules of crystals. Inorganic polymers are those structured with silicon backbones, while organic polymers with backbone of elements. (From precipitates of crude oil, known since the 2nd world war)

In the 70’s of the 20th century, mankind built a real inorganic polymer by oiling sulfer (S) powder up to 1400C, to form tiny chains of sulfur. This was a good contribution by an American team, giving rise to a revolution into the chemist circle, where the classical concept did not belief in inorganic polymerization.

Towards the 90’s of the last century, Professor Plattford of the Geology Department in Bruxelles University, has come to Vietnam and introduced a polymerization of Kaolin to form hard stones. He added NaOH to kaolin with appropriate ratio, to transform basic crystals of kaolinite into tiny magnets of microscopic size of 10Å, they attracted each other to form a hard concrete.

By the end of 90’s of the last century, and in the first decade of the 21st century, many innovations in inorganic polymers enabled us to divide them into two categories. The direct inorganic polymers like the polymerization of sulfur powder (monoatomic) or kaolinite (monomolecule) without bridging of two different materials. The indirect inorganic polymerization needs a bridging system of macrolecules made of different materials, like basic crystals of clay linked with atomic calcium.

The mechanism of linking materials is based upon magnetism born from them. A material of negative charge like clay is stick to a material of positive charge, like calcium, to form concrete sand is neutral, therefore opposes to polymerization. Magnetism in tiny particles will have a wide application and a bright future, still mysterious to mankind, as it was known only since less than two decades in Vietnam, while mankind in the world was familiar to it since six decades.

Therefore, we built as a primary step into the study of polymerization, a useful address of gathering knowledge, practices and application, of this concept and to well understand inorganic polymers. We try to obtain three categories of information: basic science, high technique and technology. We try to link theory to practice.

We welcome any contribution from you in one of the three categories in this website with thanks.
