Product Introduction

Zirconia Fiber Cotton

      Our company adopts pure inorganic reaction synthesis system, keeping the sol with high polymerization degree, high purity, continuous spinnability and long-term stability at the same time, clean, environmental protection, tasteless, pollution-free. The use of unique high pressure spinning process, continuous production of nanometer and micron zirconia fiber. Zirconia fiber high temperature vapor pressure is small, no volatilization at high temperature, clean, pollution-free. Zirconia fiber has the lowest thermal conductivity among all oxide fibers.

      Nanometer fiber cotton diameter 800-1000 nanometers, feel soft and delicate, the appearance compared with micron fiber reflects the obvious layered state, compared with micron fiber made products have lower thermal conductivity.

      The diameter of micron fiber cotton is 2-4 microns, and the appearance is stacked cotton. Compared with nanofibers, it has more advantages in cost performance.

Zirconia Fiber Products

      Zirconia fiber products are made of yttrium stabilized zirconia fiber after several processes of production of light fire-resistant energy-saving materials, compared with pure zirconia does not exist phase change. This kind of products after special process treatment, high temperature can still maintain the stability of product size. Zirconia fiber products can be processed into furnace plates, all kinds of special-shaped products; Different density of zirconia fiber products can be customized, with different strength and thermal conductivity. The product can be used in 2200 ^ºC high temperature environment. It has excellent corrosion resistance.

Basic Features

• Temperature resistance up to 2400^ºC, long-term use of 2200^ºC
• Very low thermal conductivity 0.099W/m·K(1400^ºC)
• High purity (ZrO₂+Y₂O₃) ≥99.8%
• No volatile organic residues
• Oxidation resistance, corrosion resistance chemical properties stable acid and alkali corrosion resistance
• Do not drop powder, do not drop slag appearance smooth
• The shape can be customized according to the requirements of drawings
• Density customizable products with different densities can be customized according to different application fields

Application Field

Zirconia combined temperature field for crystal growth

Design Scheme:

• The side screen temperature field is designed with two layers inside and outside. The inner layer is high-density zirconia special-shaped parts and the outer layer is low-density zirconia fiber special-shaped parts;
• Each layer is divided into several pieces, and the child buckle or "Sharp Angle" joint splicing is used between each piece, and the child buckle splicing is used between layers; The height of each layer of the inner and outer layers is different to ensure the sealing and structural stability of the temperature field.

Design Advantages:

• Compared with traditional materials, can greatly reduce the use of power, energy saving up to 40%.
• The dislocation splicing method is adopted in the layer and the layer, which can effectively prevent the cracking and light leakage of the material and ensure the stability of the temperature field of the crystal furnace.
• No volatilization under high temperature environment, reduce temperature field pollution, green environmental protection.
• The crystal quality of zirconia fiber products is better.
• Reduce the thickness of insulation material, greatly improve the utilization rate of the internal space of crystal furnace.

Zirconia fiber furnace for high temperature furnace

Design Scheme:

• The furnace adopts special structure of all zirconia fiber products furnace.

Design Advantages:

• Compared with traditional materials, can greatly reduce the use of power, energy saving up to more than 30%, the larger the furnace, the higher the temperature, the more obvious energy-saving effect.
• Using the company's special structure, can be used for a long time.
• Long-term use temperature of box furnace can reach 1800 ºC, vacuum furnace can reach 2200 ºC.

Zirconia fiber powder

      Zirconia fiber powder is made of zirconia micron fiber by special process grinding. The appearance is powdery structure, white and delicate, and the microscope is needle-like structure. It can be applied to the enhancement and toughening of various materials.
