    • PURPOSE: A milling method of a silicon carbide material is provided to improve a sinterability of a silicon carbide powder by controlling a milling atmosphere while manufacturing Si and C to the silicon carbide material powder through the high energy milling. CONSTITUTION: A milling method of a silicon carbide material comprises the following steps. A milling atmosphere is maintained as a state of vacuum while changing a raw material which includes Si and C to the silicon carbide through a planetary milling. An oxygen content of the silicon carbide which is obtained by milling in the vacuum is less than the oxygen content of the silicon carbide which is obtained in the air under the milling condition which is same with the milling condition in the vacuum. A molded product of the silicon carbide powder which is obtained by milling in the vacuum has the high sintered density at more than 2000°C of the sintering temperature. The molded product of the silicon carbide powder which is obtained by milling in the vacuum maintains the low sintering temperature in the constant sintered density.
    • 目的:提供碳化硅材料的研磨方法,以通过控制研磨气氛来提高碳化硅粉末的烧结性,同时通过高能量研磨将Si和C制造成碳化硅材料粉末。 构成:碳化硅材料的研磨方法包括以下步骤。 通过行星式研磨将包含Si和C的原料转变成碳化硅,将研磨气氛保持为真空状态。 在真空中研磨获得的碳化硅的氧含量小于在空气中在与真空中的研磨条件相同的研磨条件下获得的碳化硅的氧含量。 通过在真空中研磨获得的碳化硅粉末的成型体在烧结温度的2000℃以上具有高的烧结密度。 通过在真空中研磨获得的碳化硅粉末的成型品保持烧结温度恒定的烧结密度。

    • PURPOSE: A mold for mass synthesis of ceramic powder by spark plasma sintering is provided to uniformly mass synthesize ceramic powder by forming a plurality of pipes in which material powder is loaded. CONSTITUTION: A mold for mass synthesis of ceramic powder by spark plasma sintering comprises a body(101) which includes more than two pipes in which material powder is loaded and a pair of metal covers(102,103) which are respectively in contact with top and bottom parts of the body. The amount of raw material for the sintering of spark plasma is controlled by adjusting the height of the mold. Amounts of current and voltage for powder synthesis are minimized by forming one or more processing portions between the pipes so that the cross section of the mold body can be reduced. The peripheral or inner circumferential part of the cross section of the body has either a circular, ellipsoid, or polygonal shape.
    • 目的:提供一种通过放电等离子体烧结来大量合成陶瓷粉末的模具,通过形成多个装有材料粉末的管道来均匀地大量合成陶瓷粉末。 构成:用于通过放电等离子体烧结来大量合成陶瓷粉末的模具包括:主体(101),其包括多于两个其中装载有材料粉末的管和分别与顶部和底部接触的一对金属盖(102,103) 身体部位。 通过调整模具的高度来控制用于烧结等离子体的原料的量。 通过在管之间形成一个或多个处理部分使粉末合成的电流和电压量最小化,使得可以减小模具体的横截面。 本体的横截面的周边或内周部分具有圆形,椭圆形或多边形形状。
