Mullite-containing ceramics prepared from compositions - illite clay and aluminium hydroxide has been studied. High-temperature resistance of samples was studied in temperature range 1200 to 15000C by measuring of the linear firing shrinkage, compression strength and phases composition after each temperature cycle. The changes in phase composition and structure shows that increase of content of new formations of mullite with an incressing of testing temperature takes place along with growth of dimensions of needle-like crystals of mullite. It is considered to be the factor for the preservation of mechanical strength of samples in the range of 28-32 MPa up to 1400 0C.
