Lub cev muaj zog:
1. Thaum tshav kub kub tsis kam: qhov sib nqus melting point yog 230 degree, wool melting point yog 180 degree, thiab nws tuaj yeem khaws cia rau 1000 teev ntawm 93 degree rau -56.7 degree.
2. Kev tiv thaiv txias: -20 degree tseem tuaj yeem siv tau, qhov ntsuas kub qis dua, qhov muaj zog tensile zog, tab sis qhov ua haujlwm ntev yog txo.
3. Dej tsis kam: tuav 50 feem pua nrawm hauv dej, thiab tuaj yeem rov zoo tag nrho tom qab ziab.
4. Kev kam rau siab: Alkaline soda dej 50 feem pua, ammonia 28 feem pua, hydrochloric acid 2.5 feem pua, nitric acid qis dua 3.5 feem pua tseem tuaj yeem ua haujlwm.
