Title:
APPARATUS AND METHOD FOR MEASURING WETTING ANGLE OF REACTIVE LIQUID OXIDE AND SOLID OXIDE
Document Type and Number:
WIPO Patent Application WO/2016/171339
Kind Code:
A1
Abstract:
The present invention relates to an apparatus for measuring a wetting angle between a liquid oxide and a solid oxide, which have reactivity or solubility, and comprises: a main body comprising a heating element for heating the inside of the main body and an insulative wall; a stage located inside the main body and in which a solid-state first oxide sample is located; a drop ejector for storing a second oxide in a liquid state and dropping the liquid-state second oxide on the surface of the first oxide sample in droplet form; and an image-recording device for capturing the wetting angle of the first oxide sample and the second oxide droplets. The apparatus for measuring a wetting angle, of the present invention, comprises a separate drop ejector so as to drop a liquid oxide onto a solid sample in droplet form, and thus, compared to when conventionally applying heat in a state in which a liquid oxide is put on the surface of a solid sample, the apparatus minimizes the reaction or dissolution processing time on the contact surface of the solid oxide and the liquid oxide, thereby enabling the wetting angle measurement to be performed in a more accurate manner.
