                           The thermal stability testing and analysis of industrial grade magnesium oxide involve multiple aspects,mainly including melting point determination,thermogravimetric analysis(TGA),differential thermal analysis(DTA),etc.Here is a specific introduction to it:

                           Melting point determination:The melting point of magnesium oxide can be determined by differential scanning calorimetry(DSC).The melting point of magnesium oxide is very high,usually above 2800°C.This characteristic enables magnesium oxide to maintain excellent stability and strength in high temperature environments,making it suitable for manufacturing high-performance refractory materials.

                           Thermogravimetric analysis(TGA):Analyze the thermal stability and decomposition characteristics of magnesium oxide by measuring the mass change of the sample during heating.The thermogravimetric curve of magnesium oxide can provide information about its thermal decomposition temperature,weight loss rate,and thermal decomposition reaction.

                           Differential Thermal Analysis(DTA):By measuring the temperature changes of a sample during heating or cooling and comparing it with a reference substance,the phase transition and thermal stability of magnesium oxide can be understood.DTA can help determine the phase transition point and thermal stability of magnesium oxide at different temperatures.

                           Crystal structure analysis:X-ray diffraction(XRD)is an important method used to analyze the crystal structure of magnesium oxide.XRD can reveal the crystal structure and phase composition of magnesium oxide,which is of great significance for evaluating its thermal stability.

                           Environmental adaptability testing:The acid,alkali,and corrosion resistance of magnesium oxide are also important aspects for evaluating its thermal stability.These properties can be evaluated by testing magnesium oxide in solutions of different pH values.

                           Mechanical property testing:The hardness and compressive strength of magnesium oxide are also important indicators for evaluating its thermal stability.These properties can be measured using a Mohs hardness tester,microhardness tester,and compression testing machine.

                           Electrical property testing:The conductivity of magnesium oxide is another important aspect for evaluating its thermal stability.Although magnesium oxide usually has good electrical insulation,its conductivity may change at high temperatures,so it needs to be measured using methods such as the four point probe method.

                           Overall,the thermal stability testing and analysis of industrial grade magnesium oxide is a complex and important process that requires comprehensive evaluation from multiple perspectives.Through in-depth research and application evaluation of these technologies,the performance advantages of magnesium oxide can be better utilized and meet the growing market demand.
