2) mixed powder: the powder prepared is put in agitator mill, and the distilled water of addition 150% is stirred, and mixing time is 15 hours；
3) dry powder: the powder being stirred is loaded container, dry in the baking oven of 180 DEG C；
4) sieve powder: the powder dried is put into sieve in sieving machine uniform；
5) wrapping wire: as requested tungsten filament is coiled into the shape of needs；
6) pressure embryo: ready-made tungsten filament is put into grinding tool and is pressed into the centre of beta-silicon nitride powder；
7) sintering: put in hot pressing furnace in framed for the plain embryo loading graphite suppressed, be heated to 1700 DEG C under vacuum conditions, compressing under pressure 30 tons；
8) mill processing: the product sintered is loaded in fixture, is worked into the size of needs on flat stone mill, peripheral milling；
9) welding: the nickel wire circle of welding conduction and wire,
10) inspection: check whether product has inclined silk in detection establishing, the deviation of power, the intensity of product, the service life of product, the surface temperature of product；
11) cast: putting into alumina pedestal 4 cast detecting qualified product, filler is silica-filled dose 8；
12) assembling: the product poured into a mould is assembled with metalwork.
The invention has the beneficial effects as follows, the present invention uses special ceramic material to be prepared from, and the service life of ceramic igniter is longer, and acid-alkali-corrosive-resisting, power stability, insulation, environmental protection.
