Abstract

PURPOSE:To manufacture a specimen durable against long-term preservation and capable of fixing even light elements such as sulfur by providing a method wherein the melting is effected in two separate stages using sodium borate and lithium borate by amounts greater than respective predetermined amounts as the melting agents. CONSTITUTION:A mixture is formed by adding at least two weight parts of sodium borate to one weight part of inorganic powder as the anaylsis specimen. Then, a firtst stage of melting is conducted for 3-7min at firtst stage of melting is conducted for 3-7min at temperatures 850-950 deg.C. Subsequently, after adding at least two weight parts of lithium borate, the second stage of melting is conducted for 7- 15min at 950-1,050 deg.C. The total amount of sodium borate and lithium borate is 8-15wt%.
