Calcium monohydrate mataki karya TGA curve da DTA curve, samfurin nauyin 19mg, dumama kudin 30K / min, nitrogen yanayi. An daidaita kurkuren TGA don haka ya fara da 100%. Yankin zafin jiki na matakai uku na rashin nauyi yana da kyau a kan DTA curve na farko. A 120 ° C, calcium monohydrate rasa ruwa mai laushi. Ci gaba da dumama, calcium oxalate ba tare da matakai biyu don rushewa.

Lokacin da samfurin ya rasa abubuwa a hanyoyi daban-daban ko ya amsa da yanayin muhalli, ingancin ya canza, yana samar da matakai a kan kurkurkuren TGA, kaya a kan kurkurkuren DTA 1, yana da tasiri daban-daban da yawa da ke haifar da asarar samfurin ko samun inganci, kamar

2, tururi na volatile abubuwa, bushewa, desabsorption da adsorption na gas, ruwa da sauran volatile abubuwa, hasarar crystalline ruwa;

3, oxidation na karfe a cikin iska ko oxygen;

4, oxidation lalacewa na organic abubuwa a cikin iska ko oxygen;

5, zafi rushewa a cikin inert yanayi, tare da samar da gas. ga kwayoyin halitta, tsarin da ake kira thermolysis;

6, misali da yanayi ba daidai ba, kamar yadda aka rage tare da gas mai ƙunshi da hydrogen.

Magnetism wasu kayan canza tare da zafin jiki, zai faru Curie canji, idan gwada wannan kayan a cikin non-uniform magnetic filin, to, a Curie canji magnetic gravity canji zai samar da TGA siginar.

TGA ganewa kayan halaye
