The present invention discloses a powder material, a method for manufacturing a communication device, and a communication device. The powder material according to an embodiment of the present invention includes quartz glass powder, tungsten powder, and an auxiliary material, where a weight proportion of the quartz glass powder is 5% to 90%, a weight proportion of the tungsten powder is 5% to 90%, and a weight proportion of the auxiliary material is 0 to 20%. The powder material according to another embodiment of the present invention includes titanium powder, tungsten powder, and iron powder, where a weight proportion of the titanium powder is 4% to 80%, a weight proportion of the tungsten powder is 5% to 90%, and a weight proportion of the iron powder is 4% to 80%. The powder material according to still another embodiment of the present invention includes quartz glass powder, titanium powder, and manganese powder, where a weight proportion of the quartz glass powder is 5% to 90%, a weight proportion is 4% to 80%, and a weight proportion of the manganese powder is 4% to 80%. The powder material according to the embodiments of the present invention can be used to obtain a relatively low linear expansion coefficient, thereby implementing temperature compensation on a communication device made of the powder material. |
