Product description

Material of Ceramic electrical heater   Introduction of Silicon nitride ceramic: Silicon nitrides (Si3N4) are a range of advanced engineering ceramics  characterised by high strength, toughness and hardness and excellent chemical and thermal stability. Hot Pressed Silicon Nitride(HPSN): HPSN is made by adding a flux to a fine Si3N4 powder and then pressing the powder in a graphite die typically at 1800°C and 50MPa of pressure. The resultant body is fully dense with excellent mechanical properties Silicon nitride is a very important engineering ceramic with its own unique propertie.These include high strength, toughness and hardness, excellent wear corrosion resistance to many acids and alkalis , outstanding thermal  resistance and conduction ,electrical insulation etc.
1.Silicon nitride powder,the purity more than 99.99%. 2.Press molding of Ceramic electrical heater Silicon nitride was pressed in mold, the heating wire was embedded in it. 3. Inspecting inside by X-ray Inspecting inside heating wire is in right position or not.   4.Pressing  at 1800℃ and 50MPa of pressure. 5.Polishing 6.Testing Advantage: 1.High efficiency of heat transfer.Can save energy 2.Electrical insulation,100% safe. Even break in water, and no electricity leakage. 3.Excellent wear corrosion resistance. Can use it in any kind of water. 4. High temperature resistance:Max.1000℃ 5..Small size,easily install. 6.Health and clean 7. Long life span . 8.CE and ISO9001 certified   Products: 1) Screw thread type Ceramic electrical heater : Thread Dia.:DN25 (DN32 is optonal)  or according requirement.
