FIELD: chemistry.
SUBSTANCE: invention relates to ceramic powder, as well as a ceramic layer and a multilayer material obtained from said powder, and can be used to produce heat-insulating materials. The powder contains pyrochlore phase of general formula AxByOz c x, y = 2, z = 7, where A= Gd or Sm, or Nd, or La, or Y, B= Hf or Zr, or Ti, or Sn, C= Hf or Zr, or Ti, or Sn, and a secondary oxide CrOs with r, s>0 with content of 0.5-10 wt %. The disclosed ceramic layer (13) is obtained from said ceramic powder, wherein the multilayer material has a base (4) and said ceramic layer (13).
EFFECT: improved heat-insulating properties of the material.
