it is from the city. the BN powder to heat treatment, the oxygen content is 5 to 8% (for the central city to the BN) to reduce the heating time, the washing of the face, this is 5 or 8% amorphous boron and mixed, and the mixture of the let the image. system dynamics method on the water in the shape of the compressed image file, the reaction sintering of products generated by made of boron nitride on the product.;then the product is BN and SiC powder mixture in the ring. the heating process, and the remaining three B2O removal.;then, the decomposition of a large number of products in the SiC income for a selected methyl silane of low - viscosity and oligomer (MW wu 1000). the city, in the process, this is the product of the thickness of the hole in the SiCub85c loading.
