摘要： The object of the present invention is to provide a gas injection nozzle which is used for pouring liquid metal and which is prevented from being blocked in the course of continuous casting. According to the present invention, a gas injection nozzle for pouring liquid metal is provided, wherein(a) the nozzle consists of a porous refractory,(b) the circumference of the nozzle is surrounded by an iron shell which has a gas injection pipe, a band-like space (referred to as a gas pool hereinafter) which extends along the circumference of the nozzle perpendicular to an axis of the nozzle between the porous refractory and the iron shell, and(c) the gas pool is formed as a wavy, band-like space along at least one portion of the circumference of the nozzle.

摘要： A container for heat treatment of a positive-electrode active material of a lithium ion battery to hold raw material powder of the positive-electrode active material of the lithium ion battery when the raw material powder is subjected to heat treatment is provided. The heat treatment container contains 60 to 95 mass % of alumina and 10 to 20 mass % of silica, is free from MgO, ZrO2 and Li compounds, and has a porosity of 10 to 20%. The heat treatment container suppresses a reaction product from contaminating the raw material powder owing to suppressed reactivity with the raw material powder, and is suppressed from being cracked by thermal shock owing to the porosity in the predetermined range.
