다국어 초록 (Multilingual Abstract)

This paper is attempted to study on the variation of carbon in the productive process of we from WO₃. In order to test the variational process of carbon, furnace were used a nitrogen atmosphere and a hydrogen atmosphere.
Putting a mixture of WO₃and C into the furnaces and heating them.
The result was producted WC of good quabity. Heating the testing materials, a mixture of carbon content was changed from 1150℃ to 1650℃ in the nitrogen furnace and especially decreased at 1600℃ in the hydrogen furnace.
The severe control of the carbon content of the product was possible by this two-step carburization method.
