On the stage of material science, organopolyborosilazane (ceramizable precursor polymer) IOTA 9120 shines like a dazzling new star. With its unique composition and outstanding performance, it has become an ideal choice in numerous fields.

IOTA 9120 is a distinctive liquid precursor polymer, containing both repeating Si - N units and Si - N - B units. This unique structure endows it with a dual identity. It can be used not only as a thermosetting resin but also as a ceramic precursor, capable of transforming into a temperature - resistant SiBCN ceramic product under relatively mild conditions, as if possessing a magical "shape - shifting" ability.

Its curing methods are extremely flexible and diverse, which is truly eye - catching. Under the condition of 120 - 180℃, it can achieve cross - linking curing in air or an inert atmosphere, like a highly adaptable dancer who can perform gracefully in different environments. It can also undergo a hydrosilylation reaction using a platinum catalyst and complete curing at 80 - 100℃. The curing time is generally 2 - 5 h, depending on the curing temperature and the amount of catalyst, similar to a performer who can adjust the rhythm flexibly according to instructions.

The pyrolysis process of the cured product is full of mysteries. After high - temperature pyrolysis, it first transforms into an amorphous ceramic. Below 1600℃, it exists in an amorphous state, and above 1600℃, it begins to crystallize. Moreover, the composition of the ceramic product is closely related to the pyrolysis atmosphere. Different substances are generated under different atmospheres. For example, in a nitrogen or argon atmosphere, SiC and Si₃N₄ are produced; in an ammonia atmosphere, mainly Si₃N₄ is formed; and in an air atmosphere, mainly SiBOCN is generated. In addition, the pyrolysis of the cured product can be affected by fillers, which in turn affects the composition of the final ceramic product.

The product characteristics of IOTA 9120 are quite remarkable. Its low viscosity makes it flow more smoothly during operation. The short curing time significantly improves production efficiency. The high ceramic yield minimizes material loss. Its excellent adhesion to metals, ceramics, and graphite is like a powerful "adhesive". It is also easy to prepare SiBCN ceramics, providing convenience for obtaining high - performance ceramic materials. However, it is sensitive to water and alcohol solvents and can undergo hydrolysis or alcoholysis reactions, leading to product deterioration. It should also avoid contact with protonic substances such as acids and bases.

In terms of application areas, IOTA 9120 truly shines. In ceramic matrix composites (CMCs) and metal matrix composites, it can significantly enhance the performance of materials. As a high - temperature adhesive, it can firmly bond various materials. In anti - corrosion coatings and high - temperature oxidation - resistant ceramic coatings, it provides reliable protection for objects. As an impregnant for ceramic preforms, it can improve the performance of the preforms. It is also applicable in the preparation of thermosetting resins and organic - inorganic hybrid materials.
