Rectangular matrix porous design alumina ceramic plate

Rectangular matrix porous design alumina ceramic plate is a special ceramic material prepared by precision molding process and high-temperature sintering technology using high-purity alumina (Al ₂ O3 content ≥ 92%) as the matrix. Its core feature lies in the collaborative design of rectangular matrix structure and three-dimensional interconnected porous network. The porosity can be accurately controlled within the range of 30% -75%, and the pore size range covers 0.1 μ m to 100 μ m. It has high strength (compressive strength ≥ 45MPa), high temperature resistance (operating temperature up to 1600 ℃), corrosion resistance (acid alkali immersion weight loss rate<0.6%), and low thermal conductivity (0.189-0.8W/(m · K)). This product breaks through the limitations of traditional dense ceramics and expands its functionality through a porous structure, becoming a key material for energy conservation, emission reduction, efficient filtration, and precision load-bearing in the industrial field.

Application Fields and Problem Solutions

1. Molten metal purification: improving the intrinsic quality of materials
   Application scenario: Continuous casting and refining process of molten metals such as steel and aluminum alloys.
   Addressing pain points: Traditional filter materials are susceptible to erosion by high-temperature metal liquids, leading to secondary contamination of impurities and affecting the mechanical properties of the finished product.
   Product advantages:
   High temperature corrosion resistance: It does not soften when working continuously at 1600 ℃, and there is no chemical reaction between the aluminum oxide substrate and the molten metal. Its service life is increased by more than three times.
   Efficient filtration: The three-dimensional through pores can intercept particles at the 0.1 μ m level, combined with the “rectification effect” to prolong the time for impurities to float, improve the purity of the steel by 40%, and significantly reduce casting porosity and cracks.
   Case verification: After a certain automotive parts manufacturer adopted this product, the tensile strength of aluminum alloy wheels increased by 15% and the scrap rate decreased by 22%.
2. Industrial liquid filtration: achieving high-precision separation
   Application scenarios: chemical wastewater treatment, food grade liquid clarification, electronic ultrapure water preparation.
   Addressing pain points: Traditional filter materials are prone to clogging, have low flux, and are difficult to tolerate strong acidic and alkaline environments.
   Product advantages:
   High flux design: When the porosity is ≥ 60%, the water treatment flux reaches 2000L/(m ² · h), which is 5 times that of polypropylene filter cartridges.
   Anti pollution regeneration: Smooth surface (friction coefficient<0.1) reduces particle adhesion, recovery rate after backwashing is>95%, and service life is extended to more than 2 years.
   Customized aperture: Adjust the aperture distribution according to requirements, for example, the food industry uses a 0.2 μ m aperture to achieve sterile filtration, and the semiconductor industry uses a 10nm aperture to intercept ion impurities.
3. High temperature insulation protection: reduce energy loss
   Application scenarios: Industrial kiln lining, aircraft engine hot end components, building fire isolation belts.
   Addressing pain points: Traditional insulation materials have high thermal conductivity, leading to energy waste and equipment thermal stress damage.
   Product advantages:
   Ultra low thermal conductivity: 0.189W/(m · K) (at a porosity of 75%), which is 60% lower than traditional alumina fiber cotton and 30% more energy-efficient.
   Thermal shock resistance: Composite ceramics containing 5% SiC do not crack when rapidly cooled from 1000 ℃ to room temperature, meeting the extreme working conditions of aerospace.
   Lightweight design: With a density of 3.5g/cm ³, it is only one-third of refractory bricks, reducing the weight of the kiln by 20% and lowering the structural load.
4. Acoustic Control: Optimizing Environmental Noise
   Application scenarios: sound-absorbing walls in subway tunnels, soundproof rooms for generator sets, and acoustic decoration in theaters.
   Addressing pain points: Traditional sound-absorbing materials are flammable, sensitive to moisture, and have poor absorption of high-frequency noise.
   Product advantages:
   Broadband sound absorption: The 20 μ m-150 μ m aperture structure has a noise absorption coefficient of 0.85 for 500Hz-5000Hz, which is 40% higher than that of glass wool.
   Environmental adaptability: Made of Class A non combustible material, with a humidity resistance of 95% RH, suitable for high humidity coastal environments.
   Case verification: After adopting this product at a subway station, the platform noise decreased from 92dB to 75dB, meeting international comfort standards.
5. Biomedical: Promoting tissue regeneration
   Application scenarios: bone defect repair, artificial joint coating, drug delivery carrier.
   Addressing pain points: Traditional metal implants are prone to stress shielding and rejection reactions.
   Product advantages:
   Biocompatibility: Complies with ISO 10993 biosafety standards, with a 35% increase in cell adhesion rate compared to titanium alloys.
   Controllable degradation: By adjusting the porosity, a degradation cycle of 6-24 months can be achieved to match the speed of bone healing.
   Clinical data: A certain tertiary hospital tracked 50 patients with femoral fractures and showed that the bone density recovery rate after using this product for repair for 6 months reached 92%, far exceeding the 85% recovery rate of autogenous bone transplantation.
