    摘要： A non-settling refractory mortar is provided, which includes 100 mass % of a ceramic powder such as cordierite, mullite, alumina, or silicon carbide, 0.5 to 1.5 mass % of a clay mineral, and a colloidal oxide solution, in which the Ca content in the total solid component is defined at 0.01 to 0.5 mass % as converted to oxide so as to be provided with a thixotropic property. As a result, the coating performance is not lowered if stored for a long period after kneading, the dimension change rate after coating is small, and cracks or gaps are not formed on the coat surface. The median diameter of ceramic powder is preferred to be 10 to 50 μm, and in order to reduce the dimension change rate after coating, the content of particles of 0.1 to 5 μm in ceramic powder is desired to be 1 to 20%.

    摘要： An improved slurry formulation for the production of a thermal and environmental barrier coatings are provided which can withstand high temperature applications. The slurry includes a combination of a coarse ceramic powder fraction having close porosity particles and a fine ceramic powder fraction. The combination of the two powders produces a bimodal particle size distribution having a controlled amount of closed porosity that imparts desirable properties to the coating produced. The finer solid particles are interdispersed within an aqueous binder to produce a ceramic matrix with sufficient mechanical strength. The closed porosity containing coarse particles are embedded within the resultant ceramic matrix and do not disintegrate under high temperature conditions to impart a temperature resistant, non-collapsing closed porosity to the coating which can also act as an environmental barrier.
