Product Description:
Bauxite, alumina or bauxite miner , main ingredients are aluminum oxide, hydrate alumina containing impurities,
is an earthy mineral.White or grey, brown yellow or light red by iron.From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3, opaque, very brittle.
Very difficult to melt.Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution.Mainly used for aluminium, refractory material.
Application:
1.Aluminium metallurgy.
2.Precision casting/Investment casting: bauxite grog fines can be made into mold for precision casting.
3.Refractory: high alumina bauxite's refractoriness can reach 1780°C.
It is charactered by good chemical stability and mechanical performance.(Al2O3 ≥48% with low Fe2O3)
4.Aluminium silicate refractory fiber: The high alumina bauxite grog can melt under2000°C-2200°C in the electric arc furnace. After a series of processing, it can become aluminium silicate refractory fiber, which can be made into fiber blanket,plate,cloth.
5.Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining performance.
6.Producing bauxite cement.
7.Abrasives.
8.Ceramics industry.
9.Chemistry industry for all kinds of aluminium compound.

- Q: what kind of refractories is used to make the industrial silicon furnace mouth long life?
- Fused zirconia corundum brick, the smelter of the glassworks is used this kind of lining, and you can contact by private letter.
- Q: what grades are fire resistance of fireproofing glass divided into?
- Fire resistance of fireproofing glass is generally divided into three levels, class A glass can satisfy the requirements of fire resistance and thermal insulation at the same time. Class B, it's a kind of fireproofing glass that can satisfy the requirements of fire resistance and heat radiation strength at the same time. Class C can satisfy the requirements of refractory integrity, if you want to know more specific requirements, you can also surf the internet for a more detailed description.
- Q: What are the physical properties of refractory material?
- The mechanical properties of refractory material include compressive strength, volume density and sclerosing, slag resistance, elastic modulus, thermal shock resistance, oxidation resistance, bibulous rate, fluidity, resilience, bond strength and slump, electrical conductivity, specific heat, heat capacity, the impact strength, linear change, torsional strength, stomatal aperture distribution, resistance to acid, etc. The use performance of refractory material include refractoriness, thermal emissivity, condensation, porosity, coefficient of thermal expansion. Thermal properties of refractory material include thermal conductivity, temperature conductivity, plasticity, the hydration resistance, creep performance. The physical properties of the refractory materials include structure performance, mechanical properties, shear strength, load softening temperature, CO erosion resistance. The structure properties of the refractory materials include porosity, alkali resistance and sintering. The operating performance of refractory material include consistency, tensile strength, the use performance and operating performance, wear resistance, bending strength, thermal properties.
- Q: What kind of materials can be tested their electrical resistivity in the current refractory industry?
- fused cast bricks, fused zirconia corundum blocks, corundum, high zirconium
- Q: How much is the duration of fire resistance of the porous brick shale?
- This is really a simple question. The temperature should be limited within 1050℃, or it will be scorched. I think 980℃would be acceptable.
- Q: What is fireproofing material? Are fireproof materials the same thing with thermal insulation materials and refractories?
- Fireproofing material is inorganic board, while thermal insulation material belongs to organic board. Fireproof material can also preserve heat, but it is not as good as thermal insulation material in this aspect.
- Q: The following statement is correct: artificial corundum has a high melting point and can be used as a high grade refractory material. The main component is silica dioxide
- Artificial corundum has high melting point and can be used as high-grade refractory material. The main component is silica, and the main component is aluminaThe chemist uses agate mortar friction solid reactant without solvent synthesis, the main component of agate is the main silicate is silicon dioxideThe early construction of the Three Gorges dam uses a lot of cement, which is made of silicate materialIn the summer, tourists wear by adding cuprous oxide silica made of glass color glasses to protect eyes [] color glasses is added to the material made of silver, it is now possible to have more advanced material, but the middle school stage is said with silver bromideIt sees light, decomposes easily, and combines easily, so use it.Solar cells can be made of silicon material, and its application is favorable to environmental protection and energy saving
- Q: What are grade classifications of the external walls for fireproofing?
- The basic level can be divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indicators to make specific division, but I partly cannot report for a while, because it is very professional and technical. Please contact Qingdao Shanfang Instrument Co., LTD for details, they specialized in the external wall thermal insulation materials fire?rating testers.
- Q: What is the material of fire resistant glass reinforced plastics grating?
- What is the material of fire resistant glass reinforced plastics grating?
- Q: Are the rubber insulation materials are refractory materials?
- Compared with the fireproofing properties, the main thermal insulation properties of level B1 will be carbonized and drop when it is over 200 degree. <p class="answer-refer mt-10 f-light-gray" accuse="aRefer"> Reference: It is provided from technicians of Guangzhou Ou Fu construction materials: The answer that has been got:
