A briquette meeting required strength that is formed in an energy-saving manner from ferrous metal working scrap, such as grinding chips, and a method of making the briquette are provided. In a briquette formed by applying a pressing pressure to a ferrous metal working scrap, the percentage by weight of grinding chips is in the range of 10 wt % to 35 wt %. Viscous water-containing grinding chips crushed to a desired size and metal working scrap, such as gear cutting chips, are mixed in a feed hopper 7, and a pressing pressure is then applied to the raw mix by use of a compression pressing machine 8 to form a briquette B of ferrous metal working scrap. The content of a grinding fluid of the viscous water-containing grinding chips is 20 wt % to 60 wt %.

摘要:
A minute-particle iron oxide red pigment slurry is formed by adding sodium silicate to a minute-particle iron oxide red pigment slurry, and used to form a red filter formed between a phosphor layer of a color cathode ray tube and a panel thereof. Therefore, even if the red filter is brought in contact with a black matrix under the condition of a process of manufacturing the color cathode ray tube at high temperature, the red filter does not discolor the black matrix.
