Ultra high temperature ceramic matrix composite is a kind of high temperature structural material
with ceramic phase as the matrix, which can hold physical and chemical properties at high temperature
above 2000 ℃. It has the outstanding advantages of low density, wear resistance, excellent physical properties under high temperature, good thermochemical stability and good thermal shock resistance. Ultra high temperature ceramic matrix composite is considered to be the most Promising thermal
protection component for spacecraft materials.Composites with carbide ceramic matrixUltra high temperature carbide ceramics mainly include zirconium carbide (ZrC), hafnium carbide
(HFC), tantalum carbide (TAC), titanium carbide (TIC), etc., which have the advantages of high melting point, high temperature strength, excellent thermal conductivity and thermal shock resistance.
However, due to its brittleness and insufficient oxidation resistance, silicon carbide (SIC), zirconium borate (ZrB2), zirconia (ZrO2), molybdenum silicide (MoSi2) are often added to enhance the
mechanical properties, oxidation resistance and sintering properties of the composites are improved. The common carbide ceramic matrix composites are ZrC SiC, zrc-zrb2, zrc-zro2, zrc-mosi2, ZrC Mo, ZrC SiC CG, HFC SiC, TAC SiC, tic SiC, etc.Boride ceramic matrix composites
Ultra high temperature boride ceramics mainly include zirconium borate (ZrB2), hafnium boride (HfB2),
tantalum borate (TAB2) and titanium borate (TiB2). There are strong covalent bonds in ultra-high temperature boride ceramics, which have the advantages of high melting point, high strength, high thermal conductivity and electricity conductivity, and low evaporation rate. However, the strong
covalent bond makes it difficult to densify and sinter, and the high temperature oxidation resistance of the materials needs to be improved. ZrB2 and HfB2 are the most widely studied ultrahigh temperature boride ceramics. ZrB2 SiC and HfB2 SiC composites prepared by adding SiC can obtain higher eutectic temperature and improve the mechanical and oxidation resistance of the
Continuous fiber reinforced ceramic matrix composites Continuous fiber reinforced ceramic matrix composites are ultra-high temperature composites with ultra-high temperature ceramics or composite ceramics as matrix, such as ZrC, ZrB2, HFC,
HfB2, TAC, ZrC SiC, ZrB2 SiC, HfB2 SiC, ZrB2 ZrC SiC, etc., and reinforced by high temperature resistant fibers, such as carbon fiber (CF), silicon carbide fiber (SiCf), etc., which have excellent
properties of high strength, high toughness, low density and high temperature resistance Material.All those materials above can be industrialized In Haixin metal, with low price, high quality, we cover the full list of those materials!
