PURPOSE: To provide kiln furniture made of oxide-containing SiC, in which various characteristics such as anti-spalling, anti-oxidation and anti-creep are well balanced.

CONSTITUTION: 0.01 to 0.7wt.% V2O5, 0.01 to 0.7wt.% CaO and 0.01 to 5wt.% clay are added to SiC powder with its maximum particle diameter of 4mm or less to produce powder. The powder is baked to form SiC kiln furniture, wherein each of a surface layer and a central part of the SiC kiln furniture is measured by an X-ray refraction for powder and then a ratio of height of refraction peak value of cristobalite with 2θ being 21.9° in respect to a height of refraction peak value of silicon carbide with 2θ against CuKα ray being 34.0° is calculated. At this time, this SiC kiln furniture is made such that a rate of a value of ratio at the central part in respect to a value of ratio at the surface layer is 20% or more, a refraction strength at a normal temperature is within ±20% of a refraction strength at 1400°C.
