Zirconium Dioxide (ZrO2) is a white ceramic material with a high melting point (about 2750 ℃). Zirconia has a cubic crystal system and has a stable crystal structure at high temperatures.

In addition, zirconia has high thermal and chemical stability, which is able to maintain its performance in extreme environments. The physical properties of zirconia are very unique, with good fracture toughness, high hardness, high refractive index and low coefficient of thermal expansion. These characteristics make zirconia have a wide application prospect in many fields.

Corundum mullite plate is composed of high quality mullite and high purity fused corundum as raw materials with addition of specified binder by shaping at high pressure and sintering at high temperature. Corundum mullite material is with features of high refractoriness under load, compact structure, low porosity and high resistance to corrosion.It can work at high temperature up to 1700℃.

Cordierite Mullite kiln shelves is a high-performance refractory material composed of cordierite and mullite, which is widely used in high-temperature industrial environments.

The following is a detailed introduction to it:
Composition & Characteristics: Cordierite: Has a low thermal expansion coefficient and excellent thermal shock stability, but relatively low mechanical strength. 
Mullite: Provides high mechanical strength and high temperature resistance, but its thermal expansion coefficient is relatively high. This composite material combines the advantages of both to form a material with good thermal shock stability, high mechanical strength and strong refractory resistance, suitable for environments with high temperatures and chemical corrosion.

Our Senior refractory Silicon carbide plate is made of high purity silicon carbide material and it can offer good heat stability, high mechanical strength at high temperature, excellent thermal stability and distortion resistance at high temperature. Silicon carbide plate is widely used to fire ceramics, such as sanitary ceramic, daily ceramic, art ceramic, pottery ,porcelain tableware and so on.

Through the burning of 1400° C, its products can offer mild, bright and white enamel feeling. Our Silicon carbide plate can save the energy and increase the volume of kiln; Therefore it can increase the efficiency and economy. At the same time, our Silicon carbide  batts  is harmless to environment. Through quality product and honest cooperation, we will bring you benefit and trust. 

Sandwich sintering plate is a multi-layer plate which is mainly made of high pure mullite, corundum,ZrO2 And combined with silicon carbide,It has many advantages such as high load softening point, high stability, low pollution, good thermal shock resistance, long using life and so on.

They are excellent kiln furniture for firing PZT piezoelectric parts and other electro-ceramics, such as barium titanate (BaTiO3 ) capacitors. DZSP is dimensionally stable to 1650 °C.

They are composed of zirconia, partially stabilized with calcia, which is chemically inert and has good thermal shock resistance. It has exceptional resistance to oxidizing and reducing atmospheres at high temperatures. DZSP resists most corrosive environments, and contains no organic binders, produces no smoke and will not outgas.

Alumina ceramic column is made of high purity Al2O3 material, it is very strong. It is a good material to be used in high temperature kiln,especillay in the industry of magnetic material.When you sinter magnetic material (like soft ferrite core ), it will be necessary. Our alumina ceramic produuct is widely used in high temperature furnace,it has long using life and high strength.

Corundum mullite column is a ideal material to be used in high temperature furnace,especillay in the industry of magnetic material.

When you sinter magnetic material (like soft ferrite core ), it will be necessary. Our corundum mullite produuct is widely used in high temperature furnace,it has long using life and high strength.

Cordierite Mullite column is a high-performance refractory material composed of cordierite and mullite, which is widely used in high-temperature industrial environments. Cordierite mullite column is made from refractory materials primarily composed of cordierite and mullite.

Kerui offers a variety of types and sizes of kiln furniture. We can also customize according to customer requirements. We have production facilities and a professional technical team to provide solutions and after-sales service for our customer.

Our Senior refractory Silicon carbide column is made of high purity silicon carbide material and it can offer good heat stability, high mechanical strength at high temperature, excellent thermal stability and distortion resistance at high temperature.

The  silicion carbide is an ideal wear resistant material, which is especially suitable for the strong abrasive, coarse particles, classification, concentration, dehydration and other operations. Due to the above properties, our silicon carbide can effectively protect the part from high wear so as to prolong the service life of the equipment.
