Product Description:

High Purity Refractory Material/ Zircon Sand and Zircon Powder

1.Structure of Zircon Sand and Zircon Powder

We are offer zircon sand With Below Mention Descriptions: ZrO2 65 - 67 %.  We are offer zircon sand With Below Mention Descriptions: ZrO2 65 - 67 %. Zircon is a remarkable mineral, if only for its almost ubiquitous presence in the crust of Earth. It occurs in igneous rocks as primary crystallization products, in metamorphic rocks and in sedimentary rocks as detrital grains.   Further, the mineral due to hardness, durability and chemical inertness, zircon persists in sedimentary deposits and is a common constituent of most sands.

2.Main Features of Zircon Sand and Zircon Powder

1.Item:zircon sand  


3.Mainly used in Ceramic Industry  

4.Industry grade: ZrSiO4>99%


3.Main usage of Zircon Sand and Zircon Powder

The zircon sand is mainly used for fireproof materials (commonly called zirconium fireproof materials such as corundum bricks and zirconium fireproof fiber), sand for casting mould in casting industry (precision casting sand) and fine enamelware. In addition, the zircon sand is also used in the production of glass, metal (zirconium sponge) and zirconium compounds (zirconium dioxide, zirconium oxychloride, sodium zirconate, zirconium potassium fluoride, zirconium sulfate, etc.).

Q:What are the raw materials of refractory concrete ?
Q:As for fireproofing material rock wool and glass wool, which one is better?
Rock wool board and glass wool board are a kind of new construction thermal insulation material, it's widely applied in construction and has replaced traditional thermal insulation material to some degree. With the gradually deepening study of rock wool board, glass wool board, we can find that these insulation materials have advantages in many aspects but there are also many deficiencies, particularly there exists a lot of controversy about the impact on the human body. The production process of rock wool board and glass wool board usually includes: after melting in high temperature of rock or glass, inorganic fiber is produced by high-speed centrifugation equipment, and at the same time add binder,dust laying oil,silicone oil at certain proportion, then produce sheet material according to different requirements. It has good thermal insulation properties, mechanical property, sound absorption characteristics, belong to incombustible material and is cheap. In general, insulation, security and economy should not be contradictory, three aspects should be taken into account, balanced chosen and developed. Rock wool board and glass wool board and other such materials should be properly selected and applied to the appropriate structure, so that the choice of material will play their strengths and avoid their weaknesses.
Q:Is it normal for caable fire resistant material to catch on fire?
Abnormal; aging is certainly one of the cause of the fire. That is caused only because of poor insulation and aging caused by short circuit, but a more important reason is configuration of air switch does not meet the requirements. If the capacity of air switch equals that of the cable, trip will happen at the moment when current is overloaded, not causing a short circuit or over current fire.
Q:What are the refractory materials above 1000℃
It is a piece of cake to meet your requirement, anyway you can try unshaped castables like corundum and other refractory materials used in steelmaking which are above 1500℃ basically .
Q:how is the high-temperature flame-retardant fibre board?
The market is mainly divided into three kind of fiber. Density fiberboard, medium density fiberboard, high density fiberboard. Density fiberboard: It is rolled timber sheet made of wood shaving material produced by timber or non timber fiber that is added with or without glue or auxiliary material. A density of less than 450 kg / cubic meter, the larger fiber particles, the internal structure is not homogeneous, relatively lack of strength, lighter weight. MDF: use wood fiber or other plant fiber as material, added with glue. A sheet pressed at high temperature and pressure. A density between 450-880 kg / cubic meter, fiber particles is moderate, well proportioned internal structure, greater strength, moderate weight. HDF: Use wood fiber or other plant fiber as material, added with glue. A sheet pressed at high temperature and pressure. Its density is about 880 kg / cubic meter, small fiber particles, well proportioned internal structure, greater strength, greater weight. there are also artificial boards such as chipboard and melamine board in the market, generally used for making furnitures. the thickness of fiberboard that is produced and controlled more flexibly, is generally 5 per cent (general bulk price of 30 yuan per square meter), 9 cm (50 yuan), 18 cm (100), 25 cm (120), etc. There are thicker. However, proper deviation is acceptable. The board is usually thicker or thinner than the specified thickness. For example, It is only 16mm when specified 18mm.
Q:What is the classification standard of fireproofing material levels?
the following are the criteria: Currently fire materials levels mainly include:class A : incombustible building material,which almost doesn't burn. class A1: non-combustible, without open fire, class A2, non-combustible, it needs to measure the smoke and be qualified. class B1: nonflammable building material: nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion source. class B1: combustible building materials: combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. class B3: inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster. In addition, according to different standards, fire-proofing materials' grade partition is different: DIN4102: A1, A2, B1, B2, B3: EN13501-1 A1, A2, B, C, D, E, F
Q:What is the function of refractory in ceramics?
Refractory is used as materials of kiln,sagger and kiln car for ceramic sintering. Its refractoriness is higher than ceramics, and the essential material and tool for ceramic sintering.
Q:The classification of clay according to refractoriness, and what is the plasticity and plasticity index of clay?
Q:What level is the rock wool board fireproofing material ?
The most important feature of the rock wool board is fireproofing, which is a non-combustible material and absolute A-level! It has the specialized external wall rock wool board, which can be found online.
Q:Where is refractory used? Thank you!
According to its refractoriness, it can be divided into ordinary refractory (1,580℃ to 1,770℃), high class refractory (1,770℃ to 2,000) and super refractory (above 2,000℃); according to chemical property, it can be divided into acid , neutral and alkali refractories, and including refractory used for special occasion. The current definition of refractory do not only depend on whether the refractoriness is above 1,580℃. At present, refractory is widely used as inorganic nonmetallic material of production equipment lining in metallurgy, petrifaction, cement, ceramics, power, etc. Refractory generally has good thermal shock resistance, chemical attack resistance, low thermal conductivity and coefficient of expansion, widely used in chemical, construction material, mechanical manufacturing, and ceramics, accounting for 50% to 60% in the total output. It can resist high-temperature action. Refractory has many varieties. Refractory materials are widely used in metallurgy; chemical properties divided by acidic refractories. In addition, cement, silicates. Refractoriness refers to that when cones sample made from refractory has no load. Currently, refractory refers to that is widely used in metallurgy, including neutral refractory and basic refractory.
