SLIP CASTING METAL POWDERS: MOLYBDENUM
Technical Report
·
OSTI ID:4192793
The concepts involved in slip casting metal powders are discussed with special reference to molybdenum. It is recommended that molybdenum powder be milled to 50% less than 5 microns in an oxygen-free atmosphere. A slip may then be 1aadmup in polyvinyl alcohol solution, and after acidity adjustment to pH 6 to 7, it may be cast into ordinary ceramic grade plaster molds. A liquid to solid volume ratio of 1: 1.25 is suitable for many purposes. The effects of chemistry and vehicle dilution on the rheology of the slip are discussed. The need for balancing the advantages of small particle size powder against the reactivity of the large surface involved is stressed. It is shown that casting into sand molds is possible and has many desirable features. It is concluded that molybdenum can be slip cast in the same fashion as ceramics and that the slip behaves in the same way. Because of the greater reactivity of the metal powder, however, changes in the slip occur more quickly than in ceramic suspensions. An understanding of the principles connected with slip casting molybdenum leads to an appreciation of the factors likely to be involved in casting other metals. (auth)
