High quality customizable aluminum nitride corrosion resistant ceramic rods

Overview of Aluminum nitride corrosion-resistant ceramic rods

Aluminum Nitride Corrosion Resistant Ceramic Rod is a high-performance ceramic material product. With aluminum nitride as the main component, it has excellent corrosion resistance and can resist the erosion of many chemicals. At the same time, aluminum nitride corrosion-resistant ceramic rod also has high hardness, high strength, good thermal conductivity insulation and other characteristics. They are widely used in chemical and electronic industries for the manufacture of corrosion-resistant reaction vessels, pipelines, electrodes, etc. They can work stably for a long period of time in harsh environments and improve the service life and reliability of the equipment.

Features of Aluminum nitride corrosion-resistant ceramic rods

Aluminum nitride corrosion-resistant ceramic rods have excellent chemical stability due to their high purity and high density; not only can they resist the corrosion of strong acids such as sulfuric acid and hydrochloric acid, but they also have excellent erosion resistance to strong bases such as sodium hydroxide and potassium hydroxide.

Aluminum nitride corrosion-resistant ceramic rods have a Mohs hardness of 8 – 9, comparable to sapphire, and wear resistance far exceeds that of ordinary metal materials; even in harsh working conditions with high friction, the surface is not easy to produce abrasion and scratches. Thermal conductivity up to 170 – 230W / (m – K), equivalent to one-third of the metal copper, can quickly conduct heat out to prevent local overheating.

At the same time, aluminum nitride corrosion-resistant ceramic rods are also excellent electrical insulators, with volume resistivity greater than 10¹⁴Ω-cm, can effectively avoid circuit short circuits at high temperatures, high pressure, strong chemical corrosion and other extreme conditions but still be able to maintain good physicochemical properties for the stable operation of various types of equipment.

Applications of Aluminum nitride corrosion-resistant ceramic rods

In the chemical field, aluminum nitride corrosion-resistant ceramic rod is the core component of strong corrosive media processing equipment. Manufacturing reactor lining, it can resist sulfuric acid, nitric acid and other strong acids, as well as sodium hydroxide and other strong alkali erosion for a long time, to ensure that the reaction is safe; as a pipeline material, even in the face of the flow of high concentrations of corrosive liquids scouring, but also not easy to be destroyed, to ensure the stable operation of the chemical process.

In the electronics industry, aluminum nitride corrosion-resistant ceramic rods as integrated circuit substrate, with excellent insulation and thermal conductivity, can effectively prevent signal interference, rapid export of heat, and enhance chip performance; applied to packaging materials, can protect the chip from the external environment, but also provide stable heat dissipation channel for the chip, to protect the reliability and stability of electronic equipment.

In the metallurgical industry, the crucible made of corrosion-resistant ceramic rods of aluminum nitride can withstand the melting of high-temperature metal liquids at thousands of degrees Celsius and will not have a chemical reaction with the metal liquids; used as a water spout material; it can be used to maintain the structural integrity of the high-temperature metal liquids under the scouring of the metal liquids to control the flow rate and direction of the metal liquids.

In the field of environmental protection, in the face of acidic or alkaline wastewater treatment, its made of equipment components, such as filters, reaction tank lining, etc., can be long-term resistance to wastewater corrosion to ensure that the wastewater treatment process continues to be effective, help environmental protection equipment for long operation.

5 FAQs of Aluminum nitride corrosion-resistant ceramic rods

Q1:What are the production processes for aluminum nitride ceramic rods?

Epitaxial molding: Preparation of thin sheets by slurry coating, suitable for mass production of substrates.

Hot press sintering: Densification under high temperature and pressure to obtain high thermal conductivity.

Discharge plasma sintering: rapid sintering, reducing energy consumption and improving densification.

Metallization: Thick-film method, active brazing or direct copper cladding (DBC) to achieve connection with metal.

Q2: Why is the cost of Aluminum Nitride ceramic rods higher?

Raw material purity: high purity (>99%) aluminum nitride powder is required, and the preparation process is complicated and energy-consuming.

Production difficulty: high sintering temperature (> 1800 ℃), the need to use rare earth sintering additives and equipment investment.

Market scale: at present, it mainly relies on imports, and the cost is expected to decrease after the acceleration of the localization process.

Q3: How to extend the service life of aluminum nitride ceramic rods?

Environmental control: avoid long-term use under an oxidizing atmosphere or high temperature and pressure to prevent oxidation and brittle cracks.

Regular maintenance: Check surface cracks and wear, remove dirt, and passivate if necessary.

Stress management: Avoid excessive mechanical shocks or sudden temperature changes and reduce thermal stress.

Q4: What do I need to pay attention to when installing?

Connection method: Active brazing (e.g., Ti-based brazing material) or direct copper cladding (DBC) can be used to connect to metal parts to ensure interface strength.

Thermal conductive treatment: Use thermally conductive silicone grease or metal plating to enhance heat dissipation efficiency.

Processing accuracy: Auxiliary air pressure needs to be controlled during laser cutting to avoid heat-affected zone damage.

Q5:What are the precautions for safe handling?

Powder protection: Aluminum nitride powder may irritate the respiratory tract, so wear a mask and gloves when handling.

Disposal of waste materials: Follow environmental regulations and avoid mixing with acidic substances to prevent the generation of harmful gases.
