Claims9
Method for the quantitative determination of Al4C3, comprising the following steps:
- A. providing a gas-tight sealable autoclave;
- B. providing a substance comprising Al4C3, wherein the substance comprising Al4C3 is provided in the form of a refractory product;
- C. providing at least one aqueous liquid that reacts with Al4C3 to form at least one gas;
- D. placing the substance comprising Al4C3 and the at least one aqueous liquid in the autoclave;
- E. sealing the autoclave in a gas-tight manner;
- F. reacting the Al4C3 of the substance comprising Al4C3 and the at least one aqueous liquid in the autoclave to form the at least one gas, wherein the autoclave is under overpressure during the reaction of the substance comprising Al4C3 with the at least one aqueous liquid in the autoclave;
- G. quantitatively determining the at least one gas formed;
- and
- H. quantitatively determining Al4C3 in the substance comprising Al4C3 based on the quantitative determination of the at least one gas formed.
