Silicon Carbide 

Product Description


Black Silicon Carbide is made by a precision water classification process and air flow classification using material that is produced from the reaction between high purity silica sand and petroleum coke in a resistance-type furnace. Measuring 9.0+ on the MOHS scale of hardness, silicon carbide is one of the hardest abrasives known in the industry. The inherent friability of the sharp crystalline structure assures the continuous exposure of new cutting edges, which produces a faster and cleaner cutting performance.

Q:Is fireclay poisonous?
Refractory materials are typically oxides, alumina, magnesium oxide and aluminate cement and etc, which are non-toxic.
Q:What's the classification of refractory material?
Magnesium aluminum is complex and mainly seeing what classification standard is like according to the appearance shape can be divided into two categories, setting and not setting according to the acid alkali can be divided into acidic, magnesia, high aluminum, ramming expected, spinel, spray coating, plastic, just the quality of the jade, daub material according to the chemical composition is divided into, such as clay, neutral and alkaline according to the operation mode can be divided into different castable, magnesium, calcium, magnesium chrome
Q:Who knows the texture of fire-proof wooden door material?
The so-called fire doors are only posted a layer of fireproof material. Door selection still depends on the timber inside. The simplest way is to see the weight value, fireproof material layer, and they are generally paint-free doors. with fireproofing function..
Q:which kind of material should be used in fireproofing cabinet?
Here are a few good materials: 1. The mineral wool board, glass wool board: it mainly tales mineral wool, glass wool as insulation materials. It's non-combustible, light weight and has good high temperature resistance, but there are shortcomings ① short fiber will harm the human respiratory system, ② poor sheet strength, ③ poor barrier property of sheet for smoke of fire disaster, ④ poor decorative properity, ⑤large installment and construction work. Thus, most of the boards were sheets that take inorganic anchoring material as base material, glass wool as reinforcing material. 2. cement board: Cement board has high strength and wide sources. It is often used in fireproof suspended ceiling and partition in the past, but it has poor fire resistance and is easy to burst and lose protective function , which will limit it's applications. Cement concrete component has good thermal insulation and sound insulation properties, and it can be used as partition and roof board. Fiber reinforced cement board and other improved varieties appear in the construction materials market, and they are high strength and have good fire resistance, but their disadvantages are poor toughness, large alkalinity and poor decoration effect. 3. perlite board, cenosphere board, vermiculite board: It's a kind of hollow plate that takes low alkalinity cement as base material, perlite, glass beads, vermiculite as the aerated filling material, and is made by adding some auxiliary. It has characteristics of light weight, high strength, good toughness, fireproofing and thermal insulation, easy for construction,etc. and it can be widely used in high-rise building frame compartment, household, bathroom, kitchen, communication pipe and other non-load bearing areas.
Q:How to make the service life of refractory materials longer?
Take acid resistant refractory materials as example: the atmosphere should be acidic atmosphere, if used in an environment whose temperature is 1900℃, it would exacerbate the loss of refractory materials, so don’t use overloaded. Second, select the appropriate refractory materials according to the environment. For example, if its operating temperature is 1800℃, generally speaking, the normal use of it according to the instruction of refractory materials would be fine.
Q:What are the standards of refractory concrete ?
It can be divided into: 1. Ordinary refractory concrete Aggregates used include high alumina, clay, silica, basic materials (magnesite, chromite, dolomite, etc.) or special materials (carbon, silicon carbide, zircon, etc.). It can also use several combination of refractory material. 1. Thermal insulated refractory concrete It is mainly formulated with refractory light aggregates. The light aggregate used can be expanded perlite, vermiculite, ceramsite, porous chamotte, alumina hollow ball, etc. It can also be a combination of several refractory light aggregates or combination of the refractory aggregates. The aggluetination material used in refractory concrete can be high alumina cement, phosphate binders, water glass binder and clay, etc.
Q:What do refractory materials include?
It is so difficult.
Q:What are the new refractories?
Silicon carbide kiln furniture and mullite cordierite kiln furniture. Jing Cheng Refractories Plant in Yanshi City 0379-62222036
Q:What kind of refractory materials can withstand 1500℃ when processing briquette stove core and meanwhile cost less?
Alkali resistant castables cost the least.
Q:What refractories are resistant to fluorine gas?
It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
