0.1 kilogram of silicon carbide particle, 0.15 kilogram of the cubic boron nitride that granularity is 120-140 microns, the titanium silicide that particle diameter is 2-5 microns
Grain 0.04 kilogram, granularity be 230-280 microns 0.01 kilogram of silicon-carbide particle,
0.07 kilogram of magnesium borate crystal whisker, 0.02 kilogram of magnesia crystal whisker, 0.05 kilogram of silicon nitride fiber
1.1 kilograms of methylcellulose, 0.4 kilogram of polyvinyl alcohol, 0.5 kilogram of carboxylic propyl group guar gum, 70 kilograms of distilled water,
Preparation method：60-70 DEG C is heated the water in the container with blender again and then adds methylcellulose, polyethylene
Alcohol, carboxylic propyl group guar gum, stir evenly, sequentially add aluminium oxide, silica, boron nitride, titanium silicide, carborundum, be sufficiently stirred
When 2-4 is small, magnesium borate crystal whisker, magnesia crystal whisker, silicon nitride fiber are added, continues stirring 30 minutes, slurry is made,
Then mixing slurry is added in mould, made-up article is made,
To made-up article carry out heating, drying, drying control temperature be no more than 90 degrees Celsius, drying 48 it is small when more than, by moisture all steam
Hair falls, and is then placed in kiln firing, fires and heated using parabola heating mode, T=- 3t2+ 142t+25, wherein t are small for 0-48
When, obtain feeding tube 1 made of wear-resistant ceramic material and spiral conveyor 17.
