摘要： PURPOSE: To purify an alkali halide by a relatively simple process, without producing black foreign materials, by heating an alkali halide powder in an oxidizing atmosphere, and successively heating in a non-oxidative atmosphere until the halide is melted.
CONSTITUTION: Powder of an alkali halide such as CsI, CsBr or their mixture, etc. is heated in an oxidizing atmosphere from room temperature to a temperature between about 400°C and 500°C by increasing the temperature to the desired temperature range at a slow heating rate, i.e. about 100°C/hr, or keeping the powder at the temperature. The heat-treated alkali halide powder is heated and melted in a non-oxidative atmosphere to obtain a purified alkali halide ingot preventing the generation of black foreign materials composed mainly of carbon. The oxidizing atmosphere is preferably oxygen or an oxygen-containing gas, and the non-oxidative atmosphere is preferably hydrogen or a hydrogen-containing gas.

摘要： PROBLEM TO BE SOLVED: To provide a manufacture of natural and tasteful common salt containing the extract of bamboo. SOLUTION: This manufacture comprises the process for filling natural salt 2 in a bamboo cylinder 1 and covering it with red clay 3, the process for burning it until the bamboo on an outer side is burned out at a temperature higher than 800 deg.C which is the fusing point of sodium chloride, the process for crushing the salt burned and solidified into a powder shape and the process for repeating the processes to the salt in the same procedure for the appropriate number of times and working the salt strongly solidified by being filled in the bamboo and burned into fine powder in the final stage.
