Raw materials containing boron oxide, whether they are minerals in nature or chemical products of chemical smelting, have not been used in traditional ceramic bodies. On the one hand, the raw materials containing boron oxide are scarce and the price is relatively high; on the other hand, many functions of boron oxide in traditional ceramic bodies can be replaced by cheaper raw materials, so the use of boron oxide in the body is no longer available. Necessary. At present, almost all raw materials containing boron oxide are used in the preparation of glazes, glass and glass-ceramics. Boron Nitride
Looking at the tea sets or vases used by the ancients, you will see some brightly colored "clothes". Are these brightly colored "clothes" harmful to the human body?
The ceramics we use daily are generally dressed in smooth, smooth clothes, especially daily-use ceramics, which are more particular about "clothes", some are as white as jade, some are colorful and very beautiful. This kind of ceramic clothes is called "glaze (yòu)". The glaze in Chinese characters means oily luster, so the word "油" is used to express the luster of the surface of the porcelain, but because the word "油" represents food, it was modified by later generations to express the luster of "Cai". The word "you" in the oiled word is synthesized into the word "glaze".
Generally, the thickness of the green body glaze is 0.1 cm, but after being fired in the kiln, it adheres tightly to the porcelain body, making the porcelain compact, soft in luster, impervious to water and air, and giving people a bright mirror-like feeling. At the same time, it can improve the intensity of use, prevent pollution and facilitate cleaning. These chemical raw materials become stable after being subjected to high temperature, so tea utensils under high temperature are harmless to human body, and tea utensils of poor quality, low temperature and lead-containing are harmful to human body.
The influence of boron oxide on the melting temperature of glazes and glass-ceramics (including glass):
Boron oxide (B2O3) is one of the most effective strong fluxes. It is embodied in two aspects as a strong flux. On the one hand, the addition of boron oxide reduces the liquidus temperature of the batching system. Someone has done research, for the glass phase of borosilicate, every 1% of B2O3 can reduce the liquidus temperature by 35~60℃. The second aspect of boron oxide as a strong flux is that it accelerates and strengthens the melting process. Especially when there is less boron oxide, this accelerated melting process is more significant. It has been suggested that an average increase of 1% of B2O3 will shorten the melting time by 20% to 30%.
The influence of boron oxide on the viscosity of glaze and glass-ceramics (including glass):
The influence of boron oxide on the viscosity of glaze and glass-ceramic varies with the amount of it added and the temperature. In terms of the influence of temperature, generally speaking, in the low temperature range from the glass transition point to the softening point, it will not reduce the viscosity of the glass melt, and in the higher temperature range, B2O3 can always greatly reduce the viscosity of the system , Even in the middle temperature range of about 1100 ℃, this effect is still more obvious. The effect of boron oxide in reducing the viscosity of the system is comparable to that of zinc oxide.
