Titanium powder sintered porous metal filters are advanced filtration elements manufactured by sintering high-purity titanium powder under controlled conditions. This process forms a three-dimensional, interconnected porous network that integrates titanium’s inherent chemical stability with the permeability of porous materials. Widely recognized for their durability, precision, and resistance to harsh environments, these filters are indispensable in industries requiring high-performance separation—from water treatment to aerospace.
| Indicator | Typical Range | Industrial Significance |
|---|---|---|
| Pore Size | 0.1μm – 200μm | Defines filtration accuracy: – 0.1–0.22μm: Removes bacteria, viruses, and colloids (pharmaceutical/electronics). – 1–10μm: Filters suspended solids, algae (water treatment). – 50–200μm: Separates large particles (industrial pre-filtration). |
| Porosity | 30% – 60% | Balances flux and strength: – Higher porosity (50–60%): Larger water/gas flux (low resistance) but lower mechanical strength. – Lower porosity (30–40%): Higher compressive strength (for high-pressure systems) but reduced flux. |
| Permeability | 1–50 m³/(m²·h·kPa) | Measures the rate of fluid/gas passing through the filter. Critical for high-throughput applications (e.g., industrial wastewater treatment). |
| Corrosion Resistance | Resistant to pH 1–14 (acids/alkalis) and oxidizing media (chlorine, ozone) | Enables use in harsh environments: – Seawater (high salt content). – Acidic wastewater (electroplating, pickling). – Pharmaceutical sterilization (ozone/chlorine disinfection). |
| Mechanical Strength | Compressive strength: ≥80MPa; Tensile strength: ≥20MPa | Ensures structural stability: No deformation/cracking under high pressure (e.g., 1–5MPa in industrial pipelines) or thermal shock. |
| Operating Temperature | -200℃ – 300℃ (continuous); Up to 600℃ (short-term) | Suitable for extreme temperature scenarios: – Low-temperature: Cryogenic fluid filtration (LNG). – High-temperature: Hot gas purification (power plants) or steam sterilization (pharmaceuticals). |
Advantages Over Traditional Filters
Compared to conventional filters (PP cotton, activated carbon, ceramic, or polymer membranes), titanium powder sintered porous metal filters offer irreplaceable benefits:
No Secondary Pollution
Titanium is biochemically inert (no dissolution of heavy metals, plasticizers, or binders into the filtered medium).
The sintered structure is monolithic (no loose particles), meeting strict hygiene standards for food, pharmaceuticals (GMP compliance), and drinking water.
Exceptional Durability & Reusability
Unlike disposable PP/ceramic filters (service life: 1–3 months), titanium filters can be reused for 2–8 years (depending on application).
Broad Environmental Adaptability
Resists corrosion from seawater, acids (hydrochloric acid, sulfuric acid), alkalis (sodium hydroxide), and oxidants (chlorine, hydrogen peroxide)—a capability unmatched by stainless steel (corrodes in strong acids) or polymer membranes (swell in organics).
Withstands extreme temperatures (from cryogenic to high-heat) and pressure shocks, making it suitable for both indoor and outdoor (e.g., marine) applications.
Customizable Design
Sheet filters: Used for plate-and-frame filtration systems (food processing).
Tubular/cartridge filters: For pipeline filtration (water treatment, oil & gas).
Multi-channel filters: High-flux designs for large-scale industrial processes (power plant cooling water).
Application Fields
Titanium powder sintered porous metal filters are used in industries requiring high filtration performance, chemical stability, and reliability. Key applications include:
Water & Wastewater Treatment
Drinking Water/Mineral Water: Precision filtration to remove rust, sediment, bacteria (≥0.22μm), and colloids; used as pre-filters for reverse osmosis (RO) systems.
Seawater Desalination: Pre-filtration to remove algae, suspended solids, and sand, protecting RO membranes from fouling.
Industrial Wastewater: Filtration of acidic/alkaline wastewater (e.g., electroplating, pharmaceutical, textile) and recovery of valuable solids (e.g., catalyst particles, metal oxides).
Pharmaceutical & Biomedical
Injection Water/Purified Water: Sterile filtration (0.22μm) compliant with GMP standards; can be steam-sterilized (121℃) repeatedly without deformation.
Bioprocessing: Filtration of cell cultures, vaccines, and biopharmaceuticals (biocompatible, no adsorption of active ingredients).
Food & Beverage
Beverage Filtration: Clarification of wine, beer, fruit juice, and dairy products (removes yeast, bacteria, and pulp without affecting taste).
Edible Oil Processing: Filtration to remove impurities, free fatty acids, and particulate matter, improving oil quality and shelf life.
Chemical & Petrochemical
Catalyst Recovery: Filtration and recycling of solid catalysts (e.g., in petrochemical cracking processes) to reduce material waste.
Gas Purification: Filtration of process gases (e.g., hydrogen, nitrogen) to remove dust, oil mist, and liquid droplets.

production
1. Substrate treatment: it needs to be treated by roughing, cleaning and removing oil, which can increase the compactness of catalytic.
2. Brushing coating:After substrate treatment, it will be proceeded brush coated. The main coated content is platinum group metal, which is a kind of mixed solution.Then, heat treatment will be going on after drying.The whole procedure need to be repeated many times. This method is better to form thin oxide catalytic that is lamellar adhere to substrate surface.
