查询词典 sintering

The results show that the best sintering process for SiC preform is 1100℃, 8 h in vacuum, by which the open porosity is 99.6% and the preform strength reaches 0.57 MPa. The thermo-physical characteristics of 57% SiCp/Al composites produced by this technique are as follows: the relative density is 98.7%; the thermal expansion coefficient is 7.5×10-6 ℃-1 which almost matches those of GaAs and BeO; the thermal conductivity is 1.65×105 W/K, which corresponds to that of Cu(15%)/W and decuples that of Kovar alloy; the density is close to that of aluminum and less than that of one fifth of Cu/W.

The results showed: the sintering was improved because of the presence of the dopant.

结果表明：由于掺杂组分的存在，烧结情况得到了明显的改进。

The results show that in the sintering process of clinker more La and Ce are distributed in the silicate phase, which form into solid solution with it ; The dopping effects of La and Ce induce the aberrance of stress field of diffusive medium, which decrease the activation energy of particles diffusing, and accelerate particles diffusing during the solid state reaction.

结果表明，稀土元素La和Y在熟料煅烧过程中更多地分布在硅酸盐相中形成固溶体；稀土离子的掺杂作用，导致扩散介质中应力场的畸变，降低了质点的扩散活化能，从而对固相反应中的质点扩散起促进作用。

The reinforced nanocomposites are usually prepared by dopping particles or fibers with nanometer scale in matrix and then sintering under vacuum or by precipitating nanophase from matrix.
