Aluminum crucible is the main supporting tool in thermal analyzer and the carrier of sample. Aluminum is a silver-white metal, which is protected from reaction with air and water due to its surface oxide layer. It is easily soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solutions, and hardly soluble in water. Relative density 2.70. Melting...

Advantages of Thermal Analysis Crucible Cover: Improving the temperature distribution in the crucible is conducive to uniform temperature inside the reaction system. Effectively reduce the influence of radiation effect and sample color. Prevent the flying of extremely light fine sample powder and prevent it from drifting away with the dynamic atmosphere or being taken away in the process of vacuum...

1. Introduction to Thermal Analysis Thermal analysis (TA) is a technique that records the functional relationship between physical properties and temperature of sample under the programmed temperature conditions. The most commonly used TA methods are differential thermal analysis (DTA), differential scanning calorimetry (DSC) and thermogravimetry (TG). The most commonly used thermal analysis cruci...

Alumina ceramics are sintered under the temperature of 1450~1800℃, which contain aluminum oxide as the main raw material and 6~30% of sintering additives, such as clay, MgO, CaO, TiO. The purer alumina ceramics are, the better performance can be obtained, however the manufacturing of alumina ceramics also becomes more difficult with aluminum oxide proportion increases. Pure alumina ceramic can be ...
