Cordierite, Mullite and Silicon Carbide play an important role in refractories, as follows: 1. Cordierite *Characteristics*: low thermal expansion coefficient, good thermal shock resistance, high temperature resistance. *Application*: used in kiln furniture, refractory bricks, etc., suitable for occasions with frequent temperature changes. 2. Mullite *Characteristics*: high melting point, good mechanical strength and creep resistance. *Application*: […]

Refractory bricks for ceramic kilns Refractory brick types Clay type: suitable for parts with furnace temperature below 1000C High aluminum type: suitable for combustion chambers and high temperature areas with temperature above 1000°C Corundum bricks: mainly used in the combustion chambers of ceramic kilns Silicon carbide type: used for cabinet boards, pillars, beams, etc. of […]

Since high-temperature kilns are now the main core equipment in industrial production, they are basically all made of steel. If the kiln is not lined with refractory materials, it cannot be used, because the strength of the steel cylinder of the kiln will decrease with the increase of temperature, especially when the temperature fluctuates greatly, […]

The t and g numbers of refractory bricks represent the types and characteristics of refractory bricks. T-prefix refractory bricks are general refractory bricks suitable for various industrial furnaces, such as blast furnaces, hot blast furnaces, electric furnace roofs, etc. G-prefix refractory bricks are refractory materials specifically used for blast furnaces. These numbers usually consist of […]

difference Alumina silicate fire brick high alumina brick Element The main components are aluminum oxide (Al₂O₃) and silicate The main component is alumina (Al₂O₃), the content of which is usually above 48%. performance Refractoriness, refractoriness under load, slag resistance, thermal shock resistance and other properties will vary depending on the specific chemical composition and manufacturing […]

Before we know how heavy a refractory brick is, let’s first understand how to calculate the weight of a refractory brick. The following formula is an example: Calculation formula for refractory brick weight: m = ρv (mass = volume × density) Calculation example of refractory brick weight: Take SK-32 refractory brick, T-3 straight standard brick […]

Difference Mullite Cordierite Ingredients The main component is island aluminum silicate, the mineral composition is mainly sillimanite, and it also contains a small amount of quartz, biotite, phlogopite, chlorite, etc. The main chemical components are magnesium aluminum silicate, in which the magnesium element can be replaced by a small amount of manganese, and the aluminum […]

Silicon carbide is an important raw material for refractory materials. It is often used to manufacture refractory materials, such as silicon carbide bricks, silicon carbide castables, silicon carbide combined with silicon nitride bricks, etc. The reason why it can be used as a raw material for refractory materials is mainly because of its obvious advantages.
