Applications
Ash melting microscope
Certainly, here’s a rewritten version of the content to clarify the temperature-related stages:
- Softening Temperature: This is the point at which the edges of the sample begin to round off.
- Spheric Temperature: At this stage, the sample assumes a round shape where its height matches the size of its baseline.
- Half-Sphere Temperature: When the temperature reaches this point, the sample transforms into a half-sphere shape with a height that is half the size of its baseline.
- Flow Temperature: The sample is now nearly in a liquid state, with a size equivalent to only one-third of the half-sphere’s point.
Contact angle
Contact angle measurements are conducted as part of drop contour analysis, involving the optical evaluation of the shadow image of the droplet. Furthermore, the precise determination of the temperature-dependent contact angle is achievable using Linseis’ heating microscope.
