Bone China Manufacturers-The Difference Between Synthetic Bone Meal and Natural Bone Meal

A few days ago, I accidentally discovered that someone was talking about making bone china and adding synthetic bone meal is better than natural bone meal. I felt a bit baffled. The sense of 'justification' is that the porcelain white porcelin dinnerware made with synthetic bone meal is not bone china. Let's talk about the bone china manufacturers carefully. Natural bone meal, which uses the bones of herbivores, is obtained after cooking, degreasing, air drying, calcining and grinding. For animal bone meal, cattle bone meal is the best, because bone china fired from beef bone meal is whiter in color, while other fired bone china is yellowish in color. Of course, bone china made from beef bone meal is relatively transparent and transparent. Hardness is better. Dannon bone china uses calf bones from 2 to 4 years old, which has the lowest iron content. The bone meal made from this bone is the best bone china. Synthetic bone meal is caused by high-temperature calcination after the neutralization reaction of calcium hydroxide and phosphoric acid. made of synthetic bone meal has a certain degree of permeability, and because it contains tricalcium phosphate, the main component of bone meal, it is named New Bone China. According to the definition of bone china by bone china manufacturers, bone china is commercial china with 25% or more of natural bone meal in the raw materials. Therefore, whether the new bone china above can be called bone china or something is a matter for the benevolent to see the benevolent and the wise. The existence of such things as synthetic bone powder has a certain significance. The cost of natural bone powder as raw material for bone china is relatively high, and the higher the content of bone powder, the less the content of clay raw materials and the lower the plasticity of the green body. Therefore, the green body is in the firing process. The body is easy to deform or explode, and the process is more difficult. What a beautiful result can be achieved only after how much grind it takes-pearls. The finished bone china products that are successfully fired have the characteristics of high regularity, fine porcelain, light weight, few defects, thin walls, and low water absorption.
