In the realm of ultra-high-temperature materials, SiBCN ceramics are heralded as the "crown jewel" of next-generation ceramics, owing to their exceptional thermal stability and oxidation resistance. Yet, the gap between laboratory synthesis and engineering application—achieving cost-effective, processable routes to SiBCN ceramics with tunable composition and controllable structure—has remained a formidable challenge. Today, we present the intelligent bridge across this chasm: Organoborosilazane IOTA 9120 (Ceramizable Precursor Polymer) . This is not merely another precursor resin; it is an intelligent material platform enabling on-demand "programming" of ceramic phase composition and structure.

IOTA 9120 is a liquid polymer composed of Si-N and Si-N-B repeating units. The introduction of boron is the origin of its extraordinary capabilities: it retains the excellent processability of the polysilazane family while endowing the final ceramic product with unprecedented high-temperature stability and creep resistance.

As a resin, IOTA 9120 inherits the process-friendly DNA of the polysilazane family: low viscosity, fast curing, and versatile curing methods. It can be thermally cured at 120-180°C or rapidly crosslinked via platinum-catalyzed hydrosilylation under mild conditions of 80-100°C (2-5h). Its excellent adhesion to materials such as metals, ceramics, and graphite makes it an ideal matrix for extreme-environment composites and coatings.

Yet, its true revolutionary nature lies in the compositional programmability during the ceramic conversion stage. By precisely selecting the pyrolysis atmosphere, you can actively "customize" the phase assemblage and properties of the final ceramic:

• Nitrogen/Argon → SiC/Si₃N₄ multi-phase ceramic

• Ammonia → High-purity Si₃N₄ ceramic

• Air → Unique SiBOCN ceramic

With the introduction of functional fillers, you can further tailor the microstructure and ceramic yield, achieving precise control from amorphous (<1600°C) to crystalline (>1600°C) states. A stable ceramic yield of >50% ensures low shrinkage and high densification during conversion.

From thermal protection structures for hypersonic vehicles and matrix precursors for aerospace engine ceramic matrix composites, to neutron-absorbing materials for the nuclear industry and high-temperature coatings for semiconductor fixtures—IOTA 9120 offers a fully controllable pathway from liquid processing to ceramic performance.

Important Note: Dilute only with dry solvents. Strictly avoid contact with water, alcohols, acids, bases, and other protic substances.

Choosing IOTA 9120 means seizing the right to design and control ultimate material performance. It transforms SiBCN ceramics from "fortuitous discoveries" into "tailor-made solutions," infusing next-generation extreme-environment equipment with the certainty and confidence derived from molecular design.
