摘要： Silicon sulfide is manufactured from the fine powder of silicon having a particle size in the range of 60 to 100.mu., covered thoroughly with sulfur at lower temperature less than 700.degree. C. in vacuum. In order to produce the silicon sulfide, silicon should be ground in a non-oxidizing atmosphere to prevent the formation of a silicon oxide layer that remains in the product and degrades the purity of the product. The silicon powder is dispersed sufficiently in the molten sulfur. At this time, the quantity of added sulfur needs more than 1.1 times in comparison with the stoichiometric quantity of silicon sulfide. All surfaces of silicon powder should be covered with sulfur to avoid sintering between silicon particles in the whole process of the reaction.

摘要： A method for producing an electrochemically advantageous lithium ion-conductive solid electrolyte with high ionic conductivity, low electronic conduction and electrochemical stability is disclosed. The method comprises the steps of synthesizing lithium sulfide by reacting lithium hydroxide with a gaseous sulfur source at a temperature of not less than 130.degree. C. and not more than 445.degree. C., thermally melting plural compounds containing at least silicon sulfide and the synthesized lithium sulfide, and cooling the molten mixture. The silicon sulfide is synthesized by the steps of adding a silicon powder to molten sulfur while stirring to disperse the silicon powder in the molten sulfur and heating the silicon powder-dispersed sulfur in a reaction chamber under reduced pressure.

摘要： Provided is a method for producing a high-strength superplastic material which enables a high-strength superplastic material having a metal structure formed from fine grains to be easily obtained. After the application of an ultrasonic wave to a metal material, this metal material is subjected to a heating treatment at a temperature obtained by multiplying a melting point of the material represented by absolute temperature by 0.35 to 0.6. The most suitable metal material is a high damping metal material having a specific damping capacity of not less than 10% and, in particular, Mg or an Mg alloy.
