Many ceramic materials have been fabricated using sol-gel processing where the starting materials consist of a liquid organic precursor mixed with water and alcohol. The initial stages in sol-gel reactions require temperatures in the range of 100{degrees}C or less, and therefore appear ideally suited for processing in a conventional microwave oven. In this paper we evaluate the use of several types of thermocouple geometries for measuring the temperature of liquids, including tetraethylorthosilicate (TEOS) during microwave heating. The boiling point of water is used as a reference on which to base the accuracy of our measurements.
