  A surface tension measurement method based on the maximum bubble pressure (MBP) method was developed in order to precisely determine the surface tension of molten silicates in this study. Specifically, the influence of viscosity on surface tension measurements was quantified, and the criteria for accurate measurement were : Osamu Takeda, Hirone Iwamoto, Ryota Sakashita, Chiaki Iseki, Hongmin Zhu.   Purchase Metals Reference Book - 5th Edition.

In this study, the short drop tube was improved for the measurement at high temperatures and the surface tension of pure molten copper was measured. The sample was levitated and melted using an electromagnetic levitation.

  The principle of maximum pressure in a bubble for measurements of dynamic surface tension is realized in a fully automatically operating apparatus. The set-up yields data in the time interval from 1 ms up to several seconds and can be temperature controlled from 5° to 80°C. Experimental data obtained for different surfactants and gelatine in water and/or water/glycerine mixtures at different Cited by: Surface tension of molten metals using the sessile drop method David Richard Sageman David Richard, "Surface tension of molten metals using the sessile drop method " ().

A newly designed apparatus based on the principle of maximum bubble pressure can be used for measuring the dynamic surface tension in a time interval from 1 ms to 10 s. The surface tension values for pure liquids obtained at small lifetimes are influenced by hydrodynamic by: In particular, agreement for pure alt~nlnium has only been possible very recently: only surface tension values obtained in the last decade by means of either the sessile drop (SD) or the maximum bubble pressure (MBP) methods () converge to a value around mJ.m"2 at T= by:

Surface tension of the molten metals? Hi There, I want to know the surface tension of P91 martensitic steel and L SS in molten state. please suggest any resource for it. An improved maximum-bubble-pressure system using the sugden twin- capillary method for measuring the surface tension and density of molten metals is described. Improvements include (1) internally ground capillary tips, (2) electronic pressure transducers, (3) micrometer adjustment of immersion depth for density measurements, (3) micrometer adjustment of immersion depth for density .

Improved maximum-bubble-pressure system for measuring surface tension of molten metals. measurement of the actual surface tension while a granule is being formed. As a result of recent work during development of the Blobulator at Mintek (Sec-tion III), it has now become possible to determine the surface tensions of some of the metals and alloys that are commonly granulated. In this article, the term surface tension, rather than.
