What is ceramic fuse？
Opaque metal head, ceramic or sand fuses are quite common in many household items, from extension cords to some ceiling fans. Ceramic fuses can withstand high temperatures. To prevent the formation of conductive film, fuses with better thermal stability are usually filled with sand. When the fuse element is short circuited, a thin film is formed in the fuse barrel.
What can ceramic fuse do?
The capacity of ceramic fuse is larger than that of other fuses. This means that ceramic fuses can be used in circuits with high current. Fuses made of ceramics also prevent overheating.
How does the ceramic fuse work?
Ceramic fuses can withstand high temperatures. To prevent the formation of conductive films, fuses with better thermal stability are usually filled with sand. When the fuse element is short-circuited, a thin film is formed in the fuse barrel
Ceramic heating element
What is a ceramic heating element?
As a consumer product, ceramic heater is a space heater which uses PTC (positive temperature coefficient) ceramic heating elements to generate heat. Ceramic heaters are usually portable, usually used to heat rooms or small offices, similar to metal element fan heaters.
Are ceramic heaters more efficient?
Ceramic heaters are usually small and can be easily carried from one room to another. They are more energy efficient than other space heaters, such as radiant space heaters or oil filled space heaters. However, most ceramic space heaters work best in a small range.
How do ceramic heating elements work?
It is heat that comes from the air. ... A radiant ceramic heater works by using electricity to warm a ceramic plate, which then radiates heat into the room. A convection ceramic heater, on the other hand, adds a fan into the mix. This blows air across the ceramic parts to quickly heat the air and spread it around the room.
It's heat from the air. The working principle of the radiant ceramic heater is to heat the ceramic plate with electricity, and then the ceramic plate radiates the heat to the room. On the other hand, a fan is added to the convection ceramic heater. This blows air through ceramic parts, heats the air quickly, and spreads it throughout the room.
Standoff Ceramic Insulator
What is the application of standoff ceramic insulator？
The isolation insulator is installed far away from the electrical components it supports, and its function is essentially as a thread isolator. The most important parameters of out of zone insulator are its electrical clearance, mechanical strength and installation procedure. They are most commonly used to regulate the current in the conductor, or in the conductive elements of switchgear and transformers (although these elements are usually specified with an insulating medium rather than an arrangement). Due to the physical separation between insulator and component, the support usually controls the flow of high-level voltage and significantly reduces the probability of short circuit between components. This is a particularly useful power plant or electrical equipment, with high energy requirements and electrical sensitive equipment.
Why is ceramic suitable for standoff ceramic？
Because it can withstand high voltage or electrical stress, it can reliably regulate the charge flow. In addition, ceramics have high tensile strength, corrosion resistance and deformation resistance.
What is alumina?
Alumina is produced by sintering a tightly packed powder of alumina, including some binder materials. Commercially available grades range from 90% to 99.95%, with higher purity producing slightly higher hardness. It is possible to process alumina by diamond grinding technology. Polishing is also possible, depending on the size of the alumina particles and the production process, either extrusion or extrusion. The purity of alumina produced by global ceramics company ranges from 74% to 99.96%. These high-purity alumina are the main materials in industry, which are suitable for occasions requiring electrical isolation, wear resistance, high temperature resistance and good mechanical strength.
What is the 95% alumina？
95 alumina is the most popular ceramic material in China, because its performance is better than 92 alumina, and its price is competitive. It is widely used in the design of radiator, disc, insulator, ignitor and other complex shapes.
What are the properties of 95% alumina？
Hardness and wear resistance
Definition and uniform low erosion
High temperature and corrosion resistance

What is the 99.9% alumina？
Alumina ceramics with 99.9% alumina content. A high-purity material used for the highest integrity of one or more applications whose excellent mechanical, electrical, heat or corrosion resistance is essential.
What is cordierite used for?
Cordierite is a mineral with few industrial uses. It can be used as raw material for manufacturing ceramic parts for catalytic converter. However, synthetic cordierite is used because of its reliable supply and consistent properties.
What is steatite ceramic?
Steatite ceramics are widely used in the insulation of electrical and electronic industries. It is a lower cost material than alumina, but it has excellent electrical resistance (which can be maintained at high temperature) and medium mechanical strength.
What is Cordierite ceramics?
Cordierite ceramics is a kind of magnesium aluminum silicate with good thermal shock properties. The thermal conductivity and thermal expansion of cordierite are also very low, and the cost performance is very high. It is often used as structural ceramics of kiln furniture and other applications where the temperature changes rapidly. High density cordierite can be easily pressed into technical components, while porous cordierite has superior thermal shock performance, so it can be used in heating applications
What is the dense cordierite？
This dense cordierite is based on alkaline earth or zircon. Cordierite is often used in insulation, heating box or electrical engineering. Among these works, the most important crystalline phase cordierite (2MgO.2Al₂O₃.5MgO) and its most important properties are its low coefficient of thermal expansion and good mechanical resistance.
What is the application of dense cordierite？
1 Insulator of continuous flow electric water heater
2 Pipe heating element

4 Connect the heater
5 Heated iron cartridge
6 Gas heater insertion
7 Spark protector and catalyst carrier in automobile industry.
What is the porous cordierite？
In recent years, cordierite based porous ceramics have been paid more and more attention as light structural materials, heat insulation materials, catalyst carriers and so on. Cordierite is inert to the heating element alloy at temperatures as high as 1000 ℃ or even 1200 ℃ (there is no reaction between heating element and ceramic).
What is the application of porous cordierite？
