The invention discloses an apparatus and a method for determining high temperature wettability. The apparatus comprises a heater body, a heating portion, an extruding dripping portion, a sample supporting portion and an image acquisition and processing portion. The heater body is comprised of a stainless steel cavity, a furnace lid and a No. 3 fluorine rubber ring bolt connecting together. A shielding layer in the heating portion is arranged in the center of a furnace bottom in the heater body, and a heating member is placed at the center of the shielding layer. The extruding dripping portionis perpendicularly arranged on an upper end of the heater body, and a lower end of a thermocouple in the heating portion, a lower end of the extruding dripping portion and an upper end of a sample bench are placed in the heater body. A substrate is placed at top of the sample bench. Two sets of CCD digital cameras or CMOS high speed cameras in the image acquisition and processing portion and a light source are respectively placed at the front and rear and the left and right of the heater body, and are in a same horizontal line with a symmetric axis of a quartz glass observation window, a wallthrough hole on the shielding layer and a heating member through hole on the heating member. The invention also provides a method for determining high temperature wettability.

A thermoelectric component (5) is proposed, which has a first and a second element (10, 11) which, in the vicinity of a contact point (12), are in contact with each other, particularly in the form of a thermal contact. Furthermore, in this connection, first element (10) and/or second element (11) have a ceramic material at least in one vicinity of contact point (12). The proposed component (5) is especially suitable as a thermocouple for measuring temperature based on the Seebeck effect, or for use in a Peltier element as a thermoelectric heating element or cooling element based on the Peltier effect.

The invention discloses a method for rapidly measuring the density of a solid insusceptible to absorbing water, comprising the following steps of: during the measurement of the density of the solid, firstly, enabling the temperature of deionized water in a container holding the deionized water to be consistent with the room temperature, measuring the temperature T of the deionized water by using a thermoelectric couple, transmitting the temperature T to a computer by using a temperature acquisition system, acquiring the density rho0 of the water by the computer, wherein the fluctuation of the temperature and the volume of the deionized water is avoided during the measurement; and secondly, sequentially measuring the mass M of the solid to be measured, the mass M1 of the container after a rustproof metal wire suspending mesh bag is immersed into the deionized water and the mass M2 of the container after the solid to be measured is immersed into the deionized water by adopting the rustproof metal wire suspending mesh bag through using an electronic balance, and directly obtaining the density rho of the solid after inputting to the computer . The invention has the advantages of instantaneousness, accuracy, standard and more reasonable operation process. By using the method, the densities of various solids insusceptible to absorbing water can be rapidly and conveniently measured.
