Hello Satish Narula, As is known from the state diagrams, the melting point of all mats may vary depending on the amount of impurities in the meso. If we look at a chart of ceramics, we will find the same trend. If we are talking about the pure material that can be made of ceramics, the melting temperatures are given in the Mendelean table. For more information, would you please give more information about what type of ceramics you are using - metal ceramics, glass ceramics or other. With respect Emil Yankov
