Preparation And Properties Of Magnesium Silicate Ceramics Substrate Material

Silicon the magnesium is a ceramic the performance of the interface,it's a constant electric power and a low cost,stability good,so widely used in micro e-lectronics and electronics technologies, techniques optoelectronics technology as part of the insulation of ceramic equipment parts, ceramics kipen and high freq-uency microwave media, etc. but the silicon the preparation of magnesium faces many problems, the first is the synthetic material is difficult to hold back by next phase, there is sexual more dense, tall enough to bend the intensity of the problems that need to be further studied.This paper to MgSiO₃ and Mg₂SiO₄ to study in silicon, performance and magnesium than one design the various experiments. for MgSiO₃ and Mg₂SiO₄ preparation of the high temperature conditions is aiau ; can also be incorpora-ted in a gelatinous law at lower temperatures, but the former because conditi-ons are too hard, don't be in production by the latter involved Mg₂SiO₄ ; of a partial breakdown and complex and difficult process for production quantities. This paper uses high-energy the ball mill, begrimed high activity MgSiO₃ and Mg2SiO4 powders of, and is contrary to law begrimed single phase MgSiO₃ and Mg2-SiO4 of porcelain. according to relevant material glass etc can be justifia-bly modification, and detailed study of different ball mill process of material th-e performance effects of the performance of ceramic materials.MgSiO₃ for synthesis and Mg₂SiO₄ process, is an odd that the problem th-rough the formulation and adjustment process, begrimed single phase MgSiO₃ a-nd Mg₂SiO₄ of ceramic powders. the results show that when the molar humidit-y of si of the mg for 1:1.3, in such a burning temperature at 1280℃for 3h and single phase MgSiO₃ can be get. when the molar humidity of mg si is 2 : 1.2, 1200℃to burn 3h can make the single phase Mg₂SiO₄ powders. and use the materials powders as ground mass to serve modification. Choose 102 glass and Al₂O₃ to an end. by and by the end of the end, from the different levels and effectively reduce material wastage is a constant and medium, an increase in density of the material, china to increase the intensity of the corner. the per-formance MgSiO₃ and Mg₂SiO₄ porcelain, r as MgSiO₃:εr=6.1±0.3,tanδ=(6.2±0.2)×10^-4,Mg₂SiO₄:εr=6.3±0.2, tanδ=(9.5±0.5)×10^-3(1MHz)。...
