SIC >98% F10-F1600 black silicon carbide for refractory&abrasives
Product Description
Black Silicon Carbide is produced in a high temperature electric resistance-type furnace from a mixture of quartz sand and petroleum coke.
The hardness of black silicon carbide is greater than fused alumina but less than synthetic diamond.
Its mechancial intensity is greater than fused alumina, but is brittle and very sharp. The mineral has some electrical and heat conductivity.
Black silicon carbide is typically used for machining or finishing cast iron ,non-ferrous metals, stone, leather, rubber, and other materials where sharp cutting characteristics are important .
Black Silicon Carbide is brittle and sharp and has electrical and heat conductivity in some degree.
Aplications :
Black Silicon Carbide is suitable for make grinding wheels, cutting wheels, mounted wheels, oil stone, abrasive media, and also suitable for surface grinding, lapping or polishing.
The abrasive products made of it are suitable for working on Cast Iron, Non-ferrous Metal, Rock, Leather, Rubber, Wood, Ceramic, etc.
Black Silicon Carbide is also broadly used as high-grade refractory material and metallurgical additive.

- Q: which kind of material is chosen for fireproofing window?
- (1) the inside filler material of steel, wood frame should use incombustible material. (2) window frame uses steel frame or wooden frame with certain strength that can safeguard the integrity and stability of the components. (3) steel frame and mound layer can choose galvanized?steel?sheet or stainless steel plate. Its selection criteria conform to the article 5.1 in GB12955 Steel Fireproof Door General Technical Condition. (4) the selection criteria of wooden frame and mound layer should conform to the article 5.1 in GB12955 Wooden Fireproof Door General Technical Condition. (5) fire-resistant glass can choose test approved products without affecting the fire resistance of fireproofing windows . Light transmittance of glass should not be less than 75% of same layers commom sheet glass. (6) the sealing material between the frame and the fire-resistant glass should use flame retardant materials, it can play a role of fireproofing and smoke insulation in the fire. (7) hardware accessories should be tested qualified approved supporting product.
- Q: Does the external wall thermal insulation materials level b1 need the fire barrier zone?
- Residential buildings should meet the following requirements: 1, The height of building is greater than or equal to 100m, the combustion performance of thermal insulation material should be level A. 2, The height of building is greater than or equal to 60m but less than 100m, the combustion performance of thermal insulation material should not be less than the level B2. When using the level B2 thermal insulation material, each layer should set a horizontal fire barrier zone. 3,The height of building is be equal or greater than 24m but less than 60m, the combustion performance of thermal insulation material should not be less than the level B2. When using level B2 thermal insulation material, each two-layer should set a horizontal fire barrier zone. 4, The height of building is less than 24m, the combustion performance of thermal insulation material should not be less than the level B2. Besides, when using level B2 thermal insulation material, each three-layer should set a horizontal fire barrier zone. According to this understanding, it can not be set.
- Q: How long does it take for refractory cement to solidify?
- 1. First you should be aware of the concepts of condensation and condesation time. Refractory cement belongs unshaped refractories, which when added water or liquid binding agent to mix, the agitation material will gradually lose thixotropy or plasticity and become in a state of solidification, thus is solidified. The time needed to finish the process is called solidification time. The whole process is divided into initial and final set. When beginning to lose plasticity called the initial setting, when called plasticity completely lost the final setting. 2. For refractory cement, the solidification time depends on the matching of the material and the parts and using methods. Under normal circumstances, in order to meet the requirements of time of construction, the initial set time should be no shorter than 40min, and the final set time should be no longer than 8H 3. There are also some exceptions. When refractory cement is used for spraying and injection operation together with other refractory castable, the set time is required as short as possible, sometimes flash set is required to prevent the occurrence of peeling or collapse of the spraying layer.
- Q: What's the refractoriness and how to measure the refractoriness?
- Bottom each side length is 8 mm and upper side length is 2 mm. Under a certain temperature-rising speed, when heating, refractory's resistance to high temperature from melting is called refractoriness. The properties of cross section into an equilateral triangle and height is 30 mm. When it bends down until the vertex and chassis contact temperature is the refractoriness of sample. It bends due to the influence of its weight. Make the will-measured material into standard pyrometric cone.
- Q: What substitutes are available for high-end refractories in addition to zircon sand?
- The composite sand powder can effectively replace zircon sand, with the same operation process, less operation time and environmental protection
- Q: Who knows the external wall thermal insulation materials fire rating requirements?
- The requirements of Department of Housing and the Ministry of Public Security No. 46: Residential buildings: the height of building is greater than 100 meters, the combustion performance of insulation materials should be level A. The other civil buildings: 24≤ height
- Q: What refractories can withstand high temperature above 2100 degrees?
- You can refer to advices from the first one coupled with the second one.
- Q: How many kilns using refractories are needed? What are the furnaces respectively?
- There are many magnesia-chrome bricks and alkali insulation tiles); aluminum manufacturer roaster; The bottom of the glassworks regenerative chamber generally use the clay checker bricks, which is popularly used in many places of the steel mill. the upper of the power plant uses low pore brick and magnesia bricks. The forehearth uses the corundum bricks, and the cement plant uses dry and wet rotary?kiln (silmo brick
- Q: I am a refractory material manufacturer, sold products, money is always not back, anxious to die, what is the way?
- Looking for refractory materials network, you can conduct online transactions, funds guaranteed
- Q: I wanna ask about the thermal insulation material fire resistant level?
- The inorganic have glass wool \ foam glass Bian \ the best of organic is phenolic foam \ phenolic foam composite cement layer is level A.
