Description
Aluminum titanate rise tube is kind of Aluminum titanate ceramics, which refers to a synthetic ceramic material composed of 1 mol alumina and 1 mol titanium oxide. Melting point is 1860℃, belonging to orthorhombic crystal system. The main characteristics are low thermal expansion coefficient (0.87×10-6K-1), low thermal conductivity [1～2W/(m·K)], high temperature resistance (can work at 1400℃ for a long time), good resistance Corrosion (resistance to the corrosion of refractory metals such as copper, aluminum, and molten iron), and can withstand the thermal shock of the molten iron environment from room temperature to 1400°C. Generally, it can be formed by dry pressing, casting and extrusion, and sintered at 1400-1600°C in an oxidizing atmosphere. It can be used to prepare thermocouple protection tubes that continuously measure the temperature of molten metal, or prepare honeycomb ceramics for automobile exhaust purification, as well as engine exhaust pipe linings and piston crowns, etc.
Property of Aluminum Titanate Ceramic Dosing Tube
1. Lower coefficient of thermal expansion.
2. High temperature resistance (can be used at 1400℃)
Porous Aluminum Titanate
As the melting point of aluminum titanate is as high as 1860°C, and it has a low thermal expansion coefficient and high thermal shock resistance, it can be prepared into a porous material by adding a pore former during the synthesis process, so that it has a high specific surface area and pore connectivity. Good, strong heat resistance, high compressive strength, so it can be used in automotive catalyst converters, used to support catalysts, can also be used as a filter for refining precious metals and high-temperature gases, and as a heat radiating plate, etc.
