Ceramics for Cartridge Heater
Cartridge resistance stones are insulator stones with very high electrical insulation at high temperature values used in the manufacture of cartridge resistances. In general, they are manufactured in 2 different ways, Rollable MgO stones; It is produced with 99% MgO and is obtained by firing at very high temperatures, can be used at high watt density and high temperatures, another type is the so-called String Type Cartridges, which are more cost-effective and allow working at lower temperatures and low watt density. . Different diameters for both varieties are available in our company's stocks. You can see the products in various sizes in the table below. In case of need, it is possible to produce in different diameters and forms.Dizgi Tip Fişek Taşları (Cordierit Cartridge Rods) | Mgo Haddelenebilir Fişek Taşları (Crushable Cartridge Rods) | |||

Cartridge Stones
Cartridge stones are insulation materials used in electric resistors. They are made of high-purity magnesium oxide (MgO) and possess excellent electrical insulation, high thermal conductivity, and resistance to high temperatures.
Cartridge Stone Heaters Operating Principle
Cartridge stone heaters are insulation materials used to insulate and protect heat in electric heaters. They are produced from high-purity magnesium oxide (MgO) and possess excellent electrical insulation, resistance to high temperatures, and mechanical durability. The operating principle of cartridge stone heaters is as follows: Electric current passes through the heater wire: The electric current passing through the heater wire causes the wire to heat up. Heat is transferred to the cartridge stone: The heated heater wire transfers heat to the cartridge stone. Cartridge stone insulates heat: The cartridge stone evenly distributes heat and prevents it from spreading to the surroundings, thanks to its high thermal conductivity. Heat is retained: The cartridge stone retains heat for extended periods due to its resistance to high temperatures.
