Bulk density

After burning ceramic products, according to the burning temperature and the quality of the product, there are some holes in the product. However, there are products that do not have any holes in the pill. There may be two types of holes in the material, open pores and closed pores. The open pores of the openings on the surface of the material of the mouth of the material and so that water can enter without any hindrance. And all those holes. Glassy is a state of being surrounded by material that is inside the material, but no water or any gaseous substance can enter it. These are called closed pores. The volume we see of a perforated object or substance is not the actual volume of the object or substance. It is open hole, closed hole and

The pill component of the product is equal to the sum of the volume of the fine particles. Therefore, the sum of free pores, closed pores and particles of body material of a porous product is called the bulk volume of that product. And the volume of the product except the free was called the apparent volume or the apprentice volume and without the open hole and the closed hole

The volume of a product is called the actual volume. The density of an object is directly related to its volume. So different types of volumes have been briefly discussed. The amount of free space in a porous body can be easily determined. If a sample of a porous object is immersed in water for a long time or boiled in water, liquid will enter the porous material.
