Zirconia ceramic stirrer

In high demand industrial fields such as chemical, pharmaceutical, and material preparation, traditional metal stirrers are facing increasingly prominent problems of corrosion, pollution, and wear. Zirconia ceramic stirrers are becoming a revolutionary choice to replace traditional materials due to their excellent physical and chemical properties.

Product Core Advantage: Why Choose Zirconia Ceramics?
The excellence of zirconia ceramic stirrers lies in their unique material science properties:

1. Extraordinary wear resistance and hardness: The Vickers hardness of zirconia ceramics is second only to diamond and silicon carbide. In slurries containing high hardness particles, their service life is 5-10 times that of ordinary metals (such as 304 stainless steel), significantly reducing downtime replacement frequency and maintenance costs.
2. Excellent corrosion resistance: It has excellent corrosion resistance to most inorganic acids, alkalis, and organic media, especially suitable for strong acid (such as hydrochloric acid, sulfuric acid), strong alkali, and chloride environments, solving the pain point of stainless steel pitting in halide media.
3. Absolute cleanliness and biological inertness: The surface is dense and smooth, without pores, does not adsorb materials, and is easy to clean and sterilize. Its biological inertness meets FDA standards and is an ideal choice for preventing contamination and ensuring product purity in the pharmaceutical, food, and biotechnology fields.
4. High strength and fracture resistance: Through phase transformation toughening technology, zirconia ceramics have extremely high bending strength and fracture toughness, and can withstand mechanical stress and a certain degree of impact generated during the stirring process.
5. Lightweight design: The density is about half that of steel, which can reduce driving power, energy consumption, and reduce the load on bearings and shaft seals at high speeds.

Key industrial problems solved
Zirconia ceramic stirrers provide solutions directly to the pain points in the following industries:
Pollution problem: Eliminate the precipitation of metal ions, ensure the purity of lithium battery positive and negative electrode materials, electronic ceramic powders, and high-end pigments.
Wear and corrosion issues: In corrosive environments such as electroplating solutions, wet metallurgy, and chemical synthesis, avoid the introduction of impurities and equipment failure caused by agitator corrosion/wear.
Cleaning and hygiene issues: Meet GMP standards, ensure sterility requirements in pharmaceuticals and cell culture, and prevent batch cross contamination.
Efficiency and cost issues: The ultra long lifespan reduces spare parts inventory and replacement manpower, resulting in lower overall usage costs.

Widely applicable fields
New energy materials: uniform dispersion of nanomaterials such as lithium battery slurry (lithium iron phosphate, ternary materials, lithium cobalt oxide), graphene, carbon nanotubes, etc.
Fine Chemicals: Mixing of high viscosity or high solid content systems such as pigments, dyes, coatings, inks, pesticides, resins, etc.
Pharmaceutical and Bioengineering: Mixing and blending of vaccines, protein preparations, cell culture media, and highly active pharmaceutical ingredients (HPAPI).
Electronic ceramics: Processing of materials such as MLCC slurry, ceramic powder, electronic glass, etc. that are extremely sensitive to metal ions.
Wet metallurgy and electroplating: circulating and stirring of strong acid and strong alkaline leaching solution, precious metal recovery solution, and high-performance electroplating solution.

Customer Application Case (Anonymous)
Case A – A leading domestic lithium battery material manufacturer:
Problem: When mixing ternary positive electrode material slurry with high solid content and abrasion, the stainless steel stirrer is severely worn and needs to be replaced every 2-3 months, and there is a risk of trace metal contamination.
Our solution: We have customized a serrated disc zirconia ceramic stirrer with a diameter of 800mm for it.
Result: After 18 months of continuous use, the wear was minimal, the content of metal impurities in the slurry was significantly reduced, the overall energy efficiency of the equipment was improved, and the annual maintenance cost decreased by more than 60%.
Case B – A well-known multinational pharmaceutical company:
Problem: When producing a high-value biological agent, there are extremely strict requirements for the cleaning, sterilization, and precipitation of the mixing equipment.
Our solution: Provide a zirconia ceramic stirring system with surface mirror polishing (Ra<0.1 μ m) and a fully covered design.
Result: Perfectly passed SIP/CIP verification, with no residual dead corners and no precipitates, fully meeting FDA audit requirements and ensuring product safety.
