In ultra-high-temperature materials, SiBCN ceramics are hailed as the “crown jewel” of next-generation ceramics due to 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 formidable. Today, we present the intelligent bridge across this chasm: Organoborosilazane IOTA 9120 (Ceramizable Precursor Polymer).

IOTA 9120 is a liquid polymer composed of Si-N and Si-N-B units: pale yellow, transparent, viscosity 10,000-20,000 cP, molecular weight 700-900, solid content 99.9%. 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 with unprecedented high-temperature stability and creep resistance.

As a resin, it features moderate viscosity, fast curing, and versatile curing methods: thermal curing at 120-180°C, or rapid crosslinking via platinum-catalyzed hydrosilylation at 80-100°C (2-5h). Its excellent adhesion to metals, ceramics, and graphite makes it an ideal matrix for extreme-environment composites and coatings.

Its true revolutionary nature lies in compositional programmability during ceramic conversion. By precisely selecting the pyrolysis atmosphere, you can actively “customize” the final ceramic’s phase assemblage and properties:

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

• Ammonia → high-purity Si₃N₄ ceramic;

• Air → unique SiBOCN ceramic.

With functional fillers, you can further tailor microstructure and ceramic yield, achieving precise control from amorphous (<1600°C) to crystalline (>1600°C). A ceramic yield >50% at 800°C and ceramic density of 1.70-2.00 g/cm³ ensure low shrinkage and high densification.

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.
