Problems solved by technology

The commercially available pressurized thermogravimetric analyzer consists of a pressure-bearing balance, a quartz reaction tube, an electric furnace, a pressure-bearing shell, a console, and a gas source. Solution experiment and constant temperature gasification experiment. When experimenting in a water vapor atmosphere, water vapor has entered the balance cavity and corroded the balance, and the weighing is inaccurate. It cannot be used in corrosive atmospheres such as sulfur, nitrogen, and chlorine.

Description

technical field [0001] The invention belongs to a high-temperature pressurized thermal balance and an application method. technical background [0002] Thermobalance is an instrument for thermogravimetric analysis and thermogravimetric differential measurement of micro samples. Most of the general thermogravimetric analyzers are tested under normal pressure, and there are few high-temperature pressurized thermobalances on the market. The commercially available pressurized thermogravimetric analyzer consists of a pressure-bearing balance, a quartz reaction tube, an electric furnace, a pressure-bearing shell, a console, and a gas source. Solution experiment and constant temperature gasification experiment, when experimenting in water vapor atmosphere, water vapor has entered the balance cavity and corroded the balance, and the weighing is inaccurate, so it cannot be used in corrosive atmospheres containing sulfur, nitrogen, chlorine, etc. Contents of the invention [0003]...
