Where is the wide application of zirconia ceramics


Zirconia ceramics, an advanced structural and functional material, are no longer a novelty in the laboratory. With its outstanding comprehensive performance, it has successfully crossed over to every aspect of our lives, from daily medical care to cutting-edge technology, silently solving many key problems in various fields, and is known as the “king of high-tech ceramics”.

Core advantages:
Before understanding the specific applications, we first need to understand that zirconia ceramics are widely favored because they perfectly solve many limitations of traditional materials. Its main performance advantages include:
High strength and toughness: Its bending strength and fracture toughness are much higher than other ceramic materials, and even comparable to certain metals, solving the fatal problem of traditional ceramics being “fragile”.
Excellent wear resistance: high hardness, low coefficient of friction, great resistance to wear and scratches, and extremely long lifespan.
Excellent biocompatibility: It is non irritating, non allergic, non-toxic to human tissues, and will not be corroded by body fluids, making it an ideal medical implant material.
Low thermal conductivity: Excellent thermal insulation performance, effectively blocking heat transfer.
Corrosion resistance: It can resist the erosion of various chemical substances such as acid and alkali, and its stability far exceeds that of most metals.
Aesthetics: The color is very similar to natural teeth, appearing warm white with good translucency and glossiness.

Widely applicable fields

  1. Biomedical field: Reshaping health and vitality
    The application of zirconia ceramics in this field solves the three major challenges of biocompatibility, durability, and aesthetics.
    Dental restoration (crowns, bridges, implants)
    Addressing pain points:
  2. Replacement of metal porcelain teeth: Solved the problems that metal porcelain teeth may cause, such as gum black lines, metal allergies, and affect MRI examinations.
  3. Aesthetic requirements: Its color and translucency are comparable to real teeth, meeting the extremely high requirements for aesthetic restoration of anterior teeth.
  4. Durability: Its ultra-high strength is sufficient to withstand tremendous chewing force, avoiding the risk of porcelain breakage and fragmentation, and has a long service life.
    Specific applications: all zirconium crowns, zirconium based porcelain crowns, dental implants (abutments and overall).
    Orthopedic implants (artificial joints)
    Addressing pain points:
  5. Wear particle disease: Traditional metal/polyethylene joints produce wear particles during friction, triggering the human immune response, leading to bone resorption and implant loosening. The ultra-high wear resistance of zirconia produces almost no wear particles, greatly extending the service life of artificial joints (up to 25-30 years), especially suitable for young and active patients.
  6. Biocompatibility: Absolutely safe, with no toxic side effects.
    Specific applications: artificial hip joint ball head, knee joint replacement components, etc.

  1. Industrial sector: taking on heavy responsibilities in harsh environments
    Zirconia mainly solves the extreme working condition requirements of wear resistance, corrosion resistance, and high reliability in this field.
    Precision components and wear-resistant parts
    Addressing pain points: Replacing metal parts to solve issues such as wear, rust, and short lifespan in high-speed and highly corrosive environments.
    Specific application:
    Ceramic bearing balls and bearings: used for high-speed spindles, precision machine tools, vacuum environments (oil-free self-lubricating), and corrosive environments, with a longer and more stable lifespan than steel balls.
    Ceramic cutting tools: When processing difficult to machine materials such as cast iron and quenched steel, their efficiency and service life far exceed traditional hard alloy cutting tools.
    Textile ceramic parts, such as wire guides and splicer clamps, have smooth and wear-resistant surfaces that can effectively reduce fiber wear and improve product quality.
    Electronics and Semiconductor Industry
    Addressing pain points: Providing precision materials with high strength, high insulation, and resistance to plasma erosion.
    Specific application:
    Fiber optic core and sleeve: Their extremely low thermal expansion coefficient and ultra-high precision ensure accurate positioning and stable connection of fiber optic docking.
    Semiconductor process fixtures, such as wafer polishing pads and diffusion process blades, must be resistant to high temperatures, corrosion, and high cleanliness. Zirconia is the perfect choice.

  1. Daily Life and Consumer Electronics: Technology Empowers Quality Life
    Zirconia is quietly entering our daily lives, mainly solving the problems of product aesthetics, feel, durability, and safety.
    Smart wearables and consumer electronics
    Addressing pain points: Replacing sapphire and glass, while ensuring wear and scratch resistance (with a Mohs hardness of up to 8.5), it has better toughness (less prone to breakage) and lower cost.
    Specific applications: smartwatch case, phone back panel (such as some flagship models), headphone decoration, buttons, etc. Its warm texture and luster greatly enhance the product’s grade.
    Jewelry and Fashion Accessories
    Addressing pain points: Provides an alternative material with high hardness, never fading, brilliant luster, and much lower cost than diamonds and gemstones.
    Specific application: As an artificial gemstone (commonly known as “zircon”), it is used for decoration, watch dials, high-end buttons, etc.
    Kitchenware and daily necessities
    Addressing pain points: Thoroughly solve the problems of metal cutting tools being prone to rusting, odor, requiring frequent polishing, and traditional ceramic cutting tools having insufficient hardness.
    Specific application: Ceramic knives are one of the most famous daily products of zirconia, with long-lasting sharpness, no rust, no chemical reaction with food, and the ability to maintain the original flavor of food.
