Characteristics of mullite prepared from co-precipitated 3Al2O3·2SiO2 powders

Diphasic gels were prepared by a precipitated process from the mixed solutions of colloidal silica and aluminium nitrate. High-purity stoichiometric mullite powders were produced by calcination of the products of these gels, with an exothermic reaction occurring at 1300°C. The chemical and structural evolutions, as a function of thermal treatment, have been characterized by differential thermal analysis, thermogravimetric analysis, X-ray diffraction, infrared spectroscopy, and electron microscopy. The components of the co-precipitated gels react independently with increasing temperature up to the formation of mullite. The composition of mullite also varies with the temperature of thermal treatment. The calcined powders treated by ball-milling could be sintered into a high-density body, in spite of the occurrence of a small amount of glassy phase during sintering.

Scattering parameters of a waveguide cross junction loaded with a metallic post in the center

In this paper, the scattering parameters of a waveguide cross junction loaded with a metallic post in the center are analyzed for the first time by using the Method of Lines. The homogeneous boundary condition of the third kind and curved boundary are introduced in the formulation. Numerical results are in good agreement with the experimental data. The scattering parameters at Ka-band and W-band of the cross junctions loaded with metallic posts of different radii are presented. It is shown from the numerical results that loaded with metallic posts is an effective means for adjusting the network parameters of the waveguide cross junction to satisfy some special requirements in the design of millimeter wave components.
