SiC is widely used in semiconductors due to its excellent conductor of energy. It can be utilized for devices like Schottky diodes and MOSFETs. Furthermore, SiC makes excellent power electronics due to its resistance to high temperatures and voltages.
Silicon carbide also finds use as a metal, used for bulletproof vests and ceramic plates. It can even be shaped into crucibles for use in foundry kilns.
Reaction bonded silicon carbide (RBSIC) is a widely-used refractory ceramic. This slip-casting technology product boasts excellent hardness, wear resistance, corrosion and oxidation resistance as well as thermal shock resistance. RBSIC can be employed in beams, rollers, cooling air pipes, thermal couple protection tubes, sealing parts and other special-shaped items.
A nozzle is a device that controls the flow of fuel or other fluid through a burner. It consists of an expansion distributor, which causes the fuel to increase pressure and velocity before entering its head at the nozzle.
The nozzle is typically constructed out of stainless steel or aluminum alloy and designed to direct fuel flow directly towards the burner head where it ignites. When selecting the right nozzle for your application, make sure it meets all safety requirements.
Regular inspection and cleaning of nozzles is recommended to extend their life and ensure proper function. Furthermore, replacing the nozzle when signs of wear or damage appear is wise.
Advantages
Silicon carbide is a ceramic material commonly used in power amplifiers and Schottky diodes. It boasts excellent thermal conductivity and temperature resistance, making it an ideal material for semiconductor circuits due to its high switching capacities and low switch losses.
SiC is a lightweight ceramic known for its superior strength and corrosion- and wear-resistant characteristics. It has also been employed as fuel element insulation in high temperature reactors. Furthermore, SiC can be employed in textile machine construction where it can increase the processing speeds of yarn guides by up to 8000 m/s.
Reaction bonded or sintered silicon carbide is the most frequently used form of this material for industrial applications. It has zero porosity and more than twice the thermal conductivity of oxide-bonded SiC, as well as higher bending strength. Furthermore, it resists a wide variety of chemicals while remaining strong from room temperature up to 1,350 degC.
Refractory material such as glass is often employed in industrial kilns due to its excellent thermal conductivity and ability to raise furnace temperatures. Furthermore, it helps reduce heat loss and boost energy efficiency within a kiln.
It is an ideal solution for industries such as ceramics, chemical industry, glass and metallurgy. Additionally, it works well in kilns that run on natural gas, liquefied gas, coal gas or diesel oil.
Another useful application of silicon carbide is in fire nozzle production. This durable material offers consistent operation, uniform blasting performance and cost efficiency. Furthermore, its high wear and corrosion resistance helps extend the life of a nozzle.
Reaction bonded or sintered silicon carbide can be formed into various burner tubes, including round and square models. These nozzles have been designed to fit most existing kiln burners and utilize the ideal refractory material. They may be installed directly into the load of a kiln or tapered to increase flame exit velocity for better entrainment of atmosphere around burner, thus reducing radiant hot-spots and improving temperature uniformity around it.
Benefits
Silicon carbide (SiC) is a lightweight ceramic material with strength properties comparable to diamond and resistance to acid corrosion. It makes an ideal choice for applications requiring good erosion and abrasion resistance, making it suitable for use in various industrial settings such as spray nozzles, shot blast nozzles and cyclone components.
SiC is manufactured through chemical vapour deposition (CVD) and machined to precise tolerances using diamond grinding or lapping techniques. It finds applications across a range of industries, from electronics to chemicals and process engineering.
In the energy industry, heat exchanger plates are commonly employed to heat and separate corrosive gasses from carrier gases in heat exchanger plates. This allows heat recovery from highly concentrated sulphuric acid or hot sodium hydroxide solutions.
Australia also uses low mass materials for the production of kiln beams, burner tubes and wear liners at many mining and industrial facilities. These products boast significant energy savings as well as improved product throughput due to their lightweight nature.
Reaction bonded silicon carbide (SiSiC) is typically employed for these components, which are made from sub-micron particles of a silicon-rich carbide powder with non-oxide sintering aids. Once sintered at temperatures over 2000 deg C, they can then be machined to exact tolerances using various precision diamond grinding or lapping techniques.
These durable, thermally insulating components are used in kilns for glass, ceramics and metallurgy applications to keep the burning and oxidizing elements separate. They offer protection from damage during operation.
The material’s excellent abrasion resistance and thermal conductivity ensure long service life in these components, even under extreme working conditions. As such, it has become a go-to choice for kilns producing large amounts of highly corrosive or abrasive materials.
Silicon Carbide Burner Nozzle are suitable for firing in various types of kilns, such as roller kilns, tunnel kilns and shuttle kilns. They’re especially suitable when using natural gas, liquefied gas or diesel fuel in industries like ceramics, glass and metallurgy.

Silicon carbide burner nozzle is widely used in ceramics, electric porcelain, magnetic materials, powder metallurgy and iron and steel heat treatment processes. It offers excellent temperature resistance, oxidation resistance, strength, thermal shock resistance and thermal conductivity.
It can be used with a variety of fuels such as natural gas, liquefied gas, kerosene, diesel and even yellow phosphorus tail gas. Furthermore, its resistance to corrosives such as acid and sulfur dioxide is unbeatable.
The nozzle can be customized to the exact specifications and needs of the customer, whether it is molded, carved, milled, machined or cast into various shapes and sizes.
This lightweight material boasts properties similar to diamond, making it a great choice for applications requiring strength, erosion and corrosion resistance. It has found widespread application in nozzles for oil and gas heaters as well as industrial furnaces that need high performance.
Furthermore, its excellent heat transfer properties make it perfect for kilns and ovens that must heat a variety of materials.
Another key characteristic of Silicon Carbide Burner Nozzle is their durability and resistance to cracking. This property makes them ideal for harsh environments, as it helps keep them working longer while saving on maintenance expenses.
Different nozzle types exist, such as solid stream and fog nozzles. Solid stream nozzles typically offer 100 psi pressure with an 80-degree spray pattern.
Fog nozzles typically feature lower pressure ratings and come in various spray patterns. You can adjust the pattern by changing the angle at which the nozzle is positioned; for instance, angle it down so that it points directly at a flame to maximize its efficacy.
No matter the type of nozzle used, it must be properly installed to guarantee its functionality. Furthermore, regular cleaning is necessary to prevent gunk buildup that could clog the nozzle and hinder performance – especially when using an oil-burning stove or boiler.
