Modified Polysilazane Products
While standard Polysilazanes are commercially available, metal-modified Polysilazanes are not. Agostyx is proud to offer the following series of metal-modified Polysilazanes for high-performance applications. Included in our offerings is the Original Ceraset™ Poly(Urea)Silazane.
Poly(urea)methylvinylsilazane “PUMVS/KiON Ceraset®”
Base polymer used to prepare the metal-modified polysilazanes below, and once offered under the trade name “Ceraset®” by KiON corporation, our
poly(urea)methylvinylsilazane is a low viscosity, thermally crosslinkable SiCN precursor polymer that can be used in a variety of demanding applications including ceramic matrix composites (CMC's), non-oxide silicon ceramics manufacturing, 3D printing, and much more.
Polyzirconosilazane
With the incorporation of a significant fraction of Zirconium oxide, our
zirconosilazane can be used in the highest temperature ceramic applications. Once pyrolyzed, the zirconosilazane forms a highly thermally stable ceramic (SiCN-ZrO) that shows little to no mass loss to ~1500C. Fibers drawn from such zirconosilazanes can reach tensile strengths of 2.8GPa, with higher oxidative resistance than the un-modified ceramic.
Polytitanosilazane
High temperature and corrosion resistant ceramic phase of SiCN-TiO/N possible with this modified polymer. Both microphases of ZrO and ZrN are possible.
Polyborosilazane
Utilizing Boron’s glassy, flowable oxide phase at high temperatures, this
polyborosilazane. Helpful in preventing cracking during pyrolysis and high
temperature processing, borosilazane can predispose the oxide ceramics toward shock-resistant toughened phases like SiBCN.
Polyaluminosilazane
With several beneficial and unique attributes in the ceramic space, aluminum-modified silazane ceramics include SiAlCN, SiAlON, and SiCAlON. Properties of such ceramic phases include oxidative resistance >1400C, corrosion and oxidation resistance in 1100C water vapor environments, as well as NaCl accelerated corrosion testing.
