white tabular alumina
1.Al2O3>99.2%
2.Past ISO9001-2008

Description:Tabular Alumina is a pure sintered α-alumina materials that has been fully densified by rapid-sintering without the use of sintering aids at temperature in excess 1900°C.

Tabular Alumina has characteristic large, well developed hexagonal tablet shapedα-alumina crystals of up to 200µm length. applications include its use in electrical insulators, kiln furniture and as a catalyst support.

Q:The difference between refractory and thermal insulation material
Refractory refers to inorganic non-metallic material, whose refractoriness is not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulated material also belongs to refractory as long as its refractoriness is higher than 1,580℃.
Q:what's the standard of fireproofing material?
Class A1 is divided according to the combustion performance of GB8624-2006 building materials and products. Specific technical index requirements are: 1, the temperature rise ≤30 degrees;mass loss rate ≤50%; combustion duration time is 0; 2, main components, overall products, gross calorific value of external secondary components ≤2.0MJ/kg; any inner secondary component ≤1.4MJ/kg; (there are difference between homogeneous and non-homogeneous). Z802 building materials noninflammability testing furnace has to be used for testing technical indicators mentioned in test 1, using Z805 building materials combustion heat value to test technical indicators mentioned in test device 2.
Q:What are the differences of ceramics and refractories? Is the ceramics belonging to refractories?
They are not the same. If you say the ceramic fibers, they have some common points because the ceramic fiber is one of the refractory. It is belonged to the lightweight refractory which can be considered a new type of refractory with the main ingredient of aluminum silicate (including aluminium oxide and silicon dioxide).
Q:Can polystyrene foam color steel plate be used as decorative fireproofing material ?
As far as I am concerned, polystyrene foam color steel plate cannot be used as decorative fireproofing material. Because polystyrene flame retardant and non-flame retardant of the points, from the fire retardant is generally self-extinguishing. Polystyrene is the polymer synthesized by styrene monomer through free radicals polycondensation reaction. It is a transparent thermoplastic plastic. With above 100 ℃ glass transfering temperature,it is often used to make a variety of disposable container and disposable foam lunch box which have to withstand the boiling water temperature.
Q:How about the prospect of refractory material?
Cost reduction Refractory material is affiliated to base material factories such as steel, cement and glass. But the situation becoms more severe due to lmaterial reduction and waste. It is necessary to find a substitutional raw material.
Q:Does anyone know what is a lightweight refractory material?
Heat preservation and insulation layer used only for Thermal Equipment has poor wear resistance, loose organization and high porosity(40%~85%) . The definition of light refractory material: low thermal conductivity, good performance in thermal insulation , weak mechanical strength, low volume density(generally below 13).
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.

Reference: It is provided from technicians of Guangzhou Ou Fu construction materials: The answer that has been got:

Q:Does the refractory material used in steelmaking all refer to refractory brick?
The refractory material used in steel making doesn't all refer to refractory brick, but also includes refractory castable. The foaming agent, ladle filler sand and deoxidizer are not refractory materials but ferrous metallurgy auxiliary materials.
Q:What is the biggest difference between refractory bricks and clay refractory bricks? Where can I find information on the refractory bricks?
You can look up knowledge manual of refractory material to find phosphatic material, etc. Xinjiang refractory bricks, castable refractory, refractory material, silicious, corundum and alumina-magnesia: High alumina and clay refractory bricks can be divided into
Q:What the fireproofing materialare of the refractory kettle and where they can be sold?
Many places sell these. Nearly 10 years, can't brun when it is dry, adsorption. You can also baidu these materials. Heat transfer evenly, feldspar, clay and other raw materials with a ceramic products. Traditional casserole can not resist heat difference and also can withstand for 100 high temperature without crack. Aiming at the problem of traditional casserole, easy to crack and air permeability, people joined the spodumene on raw material, produce a high-temperature resistance casserole. It is produced after the high temperature burning makes an earthenware pot to keep the original advantages. Hebei has many places to sell these materials and is also relatively cheaper. The traditional casserole has features of not easy to transfer heat's quartz and slow cooling. Due to production technology and raw materials, it greatly improves the casserole' practicability after research and improvement.
