TEST SENSOR FOR CRYSTAL GROWTH/DISSOLUTION RATE TEST, METHOD FOR PRODUCING THE SAME, AND IN-SITU CRYSTAL GROWTH/DISSOLUTION RATE MEASURING METHOD USING THE SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a test sensor for crystal growth/dissolution rate test, which allows a crystal growth test or a crystal dissolution rate measurement in various environments, and to provide a method for producing the sensor, and to provide an in-situ crystal growth/dissolution rate measuring method using the sensor.;SOLUTION: The test sensor 5 for crystal growth/dissolution rate test is prepared by burying minerals or metal grains 2, 3 to be tested under heating into the surface of a resin sheet having excellent heat resistance and chemical resistance, for example, a PFA Teflon (R) sheet 1 and polishing them as occasion demands. The surface shape of each test sensor for crystal growth/dissolution rate test, prepared by burying the minerals or metal grains to be tested into the surface of the PFA Teflon (R) sheet 1, is measured before and after test. Then, the crystal growth rate or the dissolution rate of the minerals or the metal is searched from the difference between the surface shapes before and after test. By the method, it becomes possible to rapidly and easily perform the crystal growth test or the crystal dissolution rate measurement of minerals or metals in various environments without selecting a test place, and further, the method can be applied to a simple measurement in the order of micrometer.;COPYRIGHT: (C)2013,JPO&INPIT
