Ultra high temperature ceramic materials
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 matrix
Ultra 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.
ZrC SiC CG, HFC SiC, TAC SiC, tic SiC, etc.
Boride ceramic matrix composites
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
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.
