【Abstract】 In this paper the general physical and chemical properties of the indium which is used as a soft-metal sealant is described. Two typical indium scaling techniques, ie. heat-melted indium sealing and pressule-made indium sealing, is presented, As an example the pressure-made vacuum sealing process which is used in the development of the proximity focused image intensifier is introduecd finally.更多还原
