PURPOSE:To burn powder form with small variation in dimension and properties, easy in charge/discharge work in its burning process. CONSTITUTION:Inner boxes 3 each with powder form 6 held therein and a lid 4 put thereon are laid in plural tiers, and an unburnt material 7 capable of generating a cracked gas same in nature with the powder form 6 is put on the lid on the uppermost inner box. An outer box 1 is then charged with the resulting system followed by putting a lid 2 thereon and charging in a burning oven 12. Thence, a nonoxidative gas 15 is fed via a conductor 14 into the oven and the objective burning procedure for the powder form 6 is performed. |
