How is titanium silicide Ti5Si3 powder produced?
Generally, Ti5Si3 can be prepared by casting method, powder sintering method, rapid solidification method, self-propagating combustion method, etc. However, these methods are easy to cause pollution, the processing technology is complicated, the yield is low, and the application range is wide.
1. The present invention relates to a batch preparation method of pentatitanium trisilicate powder, characterized in that it has the following steps:
(1) Through a vacuum sintering process, the Ti 5 Si 3 compound is weighed with the molar ratio of Si powder to Ti powder of 1:1. 3:5;
(2) The sintering process used in step (1) is as follows: mix the silicon powder and titanium powder uniformly and put them in a vacuum furnace, heat up to 1350 to 1450 ℃, keep warm, and cool to room temperature with a furnace;
(3) Add the sintered material obtained in step (2) into absolute ethanol, and then put it into the ball mill tank. The sealed ball mill tank is put into a high-energy planetary ball mill using AR gas as a protective gas, and then refined by a wet ball mill method.
(4) Vacuum dry and grind the ball mill slurry obtained in step (3), and pass through a 130-mesh sieve to obtain Ti 5 Si 3 powder.
2. The batch preparation method of trisilicate intermetallic compound powder according to claim 1, wherein the vacuum degree of the vacuum furnace in the step (2) is less than 1.0×10 −2 Pa. 3.
3. The batch preparation method of trisilicate intermetallic compound powder according to claim 1, characterized in that: in the step (2), heating is performed at a rate of 20°C to 1350 to 1450°C. ℃/min, and keep the temperature for 3-5 hours.
4. The batch preparation method of trisilicate intermetallic compound powder according to claim 1, characterized in that the rotation speed of the planetary ball mill in the step (3) is 300-500RPM, and the ball milling time is 24-48 hour.
The method overcomes the shortcomings of fusion casting method, pressed powder sintering method, rapid solidification method, self-propagating combustion method, etc., which are easy to cause pollution, complicated processing technology, and low yield. The reaction process has no by-products, high powder purity, accurate control of the stoichiometric ratio of the product, low energy consumption, fine particle size, uniform product distribution, high activity, batch preparation, no pollution, and low cost.
Overview of titanium silicide Ti5Si3 powder
Ti5Si3 has good high-temperature stability, high-temperature strength and good oxidation resistance, and is expected to be used in high-temperature structural materials above 1300°C. In addition, due to its low electrical resistance and high heat resistance, Ti5Si3 is also expected to be used as raw materials for sintering by weighing Si powder and Ti powder at a molar ratio of 3:5 to prepare Ti5Si3 powder, and to synthesize Ti5Si3 compounds through a vacuum sintering process . The sintering process is as follows: heat the mixture of silicon powder and titanium powder in a vacuum furnace to 1350 1450°C, keep it warm, cool the furnace to room temperature, add the sintered product to absolute ethanol, and then enter the ball mill tank, using AR gas as Protective gas
