Abstract from DBPedia
    Sintering or frittage is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction. Sintering happens as part of a manufacturing process used with metals, ceramics, plastics, and other materials. The atoms in the materials diffuse across the boundaries of the particles, fusing the particles together and creating one solid piece. Because the sintering temperature does not have to reach the melting point of the material, sintering is often chosen as the shaping process for materials with extremely high melting points such as tungsten and molybdenum. The study of sintering in metallurgy powder-related processes is known as powder metallurgy. An example of sintering can be observed when ice cubes in a glass of water adhere to each other, which is driven by the temperature difference between the water and the ice. Examples of pressure-driven sintering are the compacting of snowfall to a glacier, or the forming of a hard snowball by pressing loose snow together. The material produced by sintering is called sinter. The word sinter comes from the Middle High German sinter, a cognate of English cinder.

    焼結(しょうけつ、英語:Sintering)は、固体粉末の集合体を融点よりも低い温度で加熱すると、粉末が固まって焼結体と呼ばれる緻密な物体になる現象。出来上がった物は焼結品などと言われる。類似用語として焼成がある。
