specific Embodiment approach 1
[0013] Specific embodiment one: this embodiment prepares Ti 3 SiC 2 The method for the bulk material is carried out as follows: 1. According to the molar ratio, 2.5 to 3.5 moles of titanium powder, 1-x to 1.5-x moles of silicon powder, x moles of silicon carbide powder and 2-x moles of carbon powder Mix, where 03 SiC 2 blocks.
[0014] In step 1 of this embodiment, absolute ethanol is added as a dispersant to mix the materials evenly, so that the liquid level of the absolute ethanol is submerged by 1-5 mm of the materials.
[0015] The purity of titanium powder, silicon powder, silicon carbide powder and carbon powder in Step 1 of this embodiment is above 98%.
[0016] The Ti produced in this embodiment 3 SiC 2 The block material has a diameter of 30-50mm and a height of 10-20mm.
specific Embodiment approach 2
[0017] Embodiment 2: The difference between this embodiment and Embodiment 1 is: 0.2
specific Embodiment approach 3
[0018] Embodiment 3: The difference between this embodiment and Embodiment 1 is that x=0.25 in Step 1. Other steps and parameters are the same as those in Embodiment 1.
