Heater Powder

MgO Heater Powder

Resistance powders (MgO), used in the manufacture of cartridge and pipe resistances, are available in 3 different types in 25 kg packages in our stocks.

High Temperature: High grade MgO (1100 C)

It is used in the manufacture of cartridge resistances and high-grade furnace resistances.

Middle Temperature: Medium MgO (900 C)

It is used in the production of dry environment resistances, liquid resistances that require high temperature and serpentine resistances.

Low Temperature: Low grade MgO (700 C)

Water to be used at low temperature is used in resistances manufactured to heat low-grade liquids.

Our low temperature MgO resistance powder is made of electrofused magnesium containing more than 93% MgO, it is calcined at high temperature and finally additives are added. The product has the following features:

Temperature resistance：Excellent electrical performance, low leakage current in low temperature conditions, and should be widely applied to low temperature heating elements, mostly for domestic appliances use.

Filling effect: Good flow properties, better density when filled into the heat pipe, hence a good thermal effect.

Our Medium Temperature MgO resistance powder is made of electrofused magnesium containing more than 97% MgO, it is calcined at high temperature and finally additives are added. The product has the following features:

Temperature Resistance: Excellent electrical performance, low leakage current under medium temperature conditions, High safety, widely applied to medium temperature heating elements.

Filling Effect: Good flow properties, better density when filled into the heat pipe, hence good thermal effect.

Our High Temperature MgO resistance powder is made of magnesium containing more than 98% MgO, which is electrofused first, additives added second, and molten by high temperature calcinations third. The product has the following features:

Temperature resistance: Excellent electrical performance, low leakage current under high temperature conditions, High safety, widely applied to air-heating elements. It provides very good efficiency especially in cartridge resistances.

Filling effect: Good flow properties, better density when filled into the heat pipe, hence good thermal effect.
