Why is the color of the semi-finished ceramic ball yellow, and the inert ceramic ball after sintering is white? There are even pure white ones

Each product production method has advantages and disadvantages, the same manual ceramic ball is made by hand, its disadvantage is that the production cost is higher than the mechanical production, and the advantage is that its compressive strength is very good

This is a real picture taken by the manufacturer of the manual inert ceramic ball with a diameter of 50mm. The larger the diameter of the inert porcelain ball, the more difficult the water inside it is to volatilize, so the production cycle of the 50mm inert porcelain ball will be slightly longer

Handmade ceramic balls are hand kneaded: craftsmen directly shape the clay into a spherical shape by hand. This method can give ceramic balls a unique handmade texture, but it requires high craftsmanship from craftsmen, and the size and shape of the ceramic balls produced may vary to some extent.

When making handmade inert ceramic balls, craftsmen first accurately mix ceramic raw materials such as kaolin, alumina, etc. Unlike large-scale mechanical production, manual mixing allows for more precise control of the proportion and uniformity of raw materials. During the molding process, craftsmen manually knead and knead the raw materials into spherical shapes. This manual molding method can provide more personalized control over the shape and size of ceramic balls. Although the production efficiency is lower than mechanical production, it can meet the needs of some special specifications or small batch production.

Handmade inert ceramic balls are ceramic products used in industrial fields such as chemical and petrochemical industries. It is mainly made of ceramic raw materials and has a spherical shape. It plays a supporting, covering or dispersing role in various chemical reactors, adsorption towers and other equipment. Due to its relatively stable chemical properties, it is called an "inert" ceramic ball.

This is the finished product of high alumina ceramic ball, which is pure white when sintered
