About 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℃.In addition, because of its low electrical resistance and thermal resistance, Ti5Si3 is also promising for electrical connection structures and diffusion barrier layers.Ti5Si3 powder can be prepared by weighing Si powder and Ti powder at the molar ratio of 3∶5 as raw materials for sintering, and Ti5Si3 compound can be synthesized by a vacuum sintering process. The sintering process is as follows: The mixture of Si powder and Ti powder in a vacuum furnace, heating up to 1350 1450℃, heat preservation, with the furnace cooling to room temperature, the sintered material is added to the anhydrous ethanol, and then into the ball mill tank, with AR gas as a protective gas, the sealed ball mill tank into the high-energy planetary ball mill, the use of wet ball mill method for refinement,) The obtained ball milling slurry was dried and ground in a vacuum, and Ti5Si3 powder was obtained by passing through a 130-mesh sieve.

How is Titanium Silicide Ti5Si3 Powder Produced?
Usually, Ti5Si3 can be prepared by casting method, powder sintering method, rapid solidification method, self-propagating combustion method and so on. But these methods are easy to cause pollution, complex processing technology, low yield and limited.
1. The invention relates to a batch preparation method for trisilicate Penta-titanium intermetallic compound powder, which is characterized by the following steps:
(1) Ti5Si3 compound was synthesized by vacuum sintering process by weighing Si powder and Ti powder at the molar ratio of 3∶5;
(2) The sintering process adopted in Step (1) is as follows: place evenly mixed Si powder and Ti powder in a vacuum furnace, raise the temperature to 1350-1450℃, hold the heat, and cool to room temperature with the furnace;
(3) The sintered materials obtained in step (2) were added into anhydrous ethanol and then loaded into a ball mill tank. The sealed ball mill tank was put into a high-energy planetary ball mill with AR gas as the protective gas and then refined by the wet ball mill method.
(4) The ball milling slurry obtained in Step (3) was vacuum dried and ground, and Ti5Si3 powder was obtained by passing through a 130-mesh sieve.
2. According to the batch preparation method of trisilicate intermetallic compound powder mentioned in Claim 1, its characteristic is that the vacuum degree of the vacuum furnace in the said step (2) is less than 1.0×10-2Pa.
3. According to the batch preparation method of a trisilicate intermetallic compound powder mentioned in claim 1, the characteristics of the method are as follows: in the said step (2), the temperature is heated to 1350-1450℃ at a speed of 20℃/min, and the temperature is held for 3-5 hours.
4. According to the batch preparation method of trisilicate intermetallic compound powder mentioned in claim 1, the characteristics of the method are that the rotational speed of the planetary ball mill in the said step (3) is 300-500 RPM and the ball grinding time is 24-48 hours.
This method of batch preparation of trisilicate Penta-titanium intermetallic compound powder, according to the molar ratio of 3∶5 weighing Si powder and Ti powder as raw materials for sintering, using vacuum sintering process to synthesize Ti5Si3 compound, the sintering process is: The mixture of Si powder and Ti powder in a vacuum furnace, heating up to 1350 1450℃, heat preservation, with the furnace cooling to room temperature, the sintered material is added to the anhydrous ethanol, and then into the ball mill tank, with AR gas as a protective gas, the sealed ball mill tank into the high-energy planetary ball mill, the use of wet ball mill method for refinement,) The obtained ball milling slurry was dried and ground in a vacuum, and Ti5Si3 powder was obtained by passing through a 130-mesh sieve. This method overcomes the defects such as melting casting method, powder pressing sintering method, rapid solidification method and self-spreading combustion method, which are easy to cause pollution, complex processing technology and low yield. The reaction process has no by-products, high purity of a powder, and can accurately control the stoichiometric ratio of products, low energy consumption, fine particle size and uniform distribution of products, high activity, can be batch preparation, no pollution, cost reduction.
