Electrical performance, in a broad sense, refers to various electrical characteristics exhibited by materials under the influence of an applied electric field. For powder materials (especially inorganic insulating powders), the following core indicators are usually of concern:

Bulk density, also known as apparent density or packing density, refers to the mass per unit volume of a powder in its naturally accumulated state, without external pressure.

Simply put, modification is the process of purposefully adjusting the surface or internal properties of a material through physical, chemical, or mechanical means to obtain properties that it previously lacked or possessed insufficiently, in order to adapt it to specific applications.

Oil absorption value refers to the volume (in milliliters) of liquid required per 100 grams of powder material to absorb a specific liquid (commonly linseed oil or castor oil) to achieve a specific viscosity (such as forming a uniform agglomerate or paste). The unit is usually mL/100g.
