Bone porcelain glaze 01

Glaze is a layer of vitreous body, on the surface of the bone China is the dress of the bone China products, the stand or fall of bone porcelain glaze directly determines the product class. Bone porcelain glaze is usually transparent body, good gloss and hardness. The role of bone porcelain glaze is: (1) can override the bone porcelain on the surface of the billet surface pore and tiny rough, make bone China products surface smooth, dense impervious, airtight, not easily dirty; (2) can improve the chemical stability of bone China products, mechanical strength and thermal stability, etc. ; (3) can make the bone porcelain products more beautiful. The role of bone porcelain glaze, characteristics and types. The functions and properties of bone porcelain glaze ceramic billet surface on the glazing is aimed at improving performance and appearance quality of billet surface and improve mechanical properties of bone China products, it makes bone China increased mechanical strength, thermal stability, dielectric strength and prevent the erosion of liquids, gases, and play the role of to decorate the bone porcelain products. Through the glazing and glaze to burn, bone China, Bone China) The surface more smooth and beautiful. Bone porcelain glaze itself is glass material. Bone porcelain glaze has the similar properties to glass, but at the same time also has the characteristics of different from the glass. A notable features are fused glaze between components in the reaction degree and the uniformity of melt quality of the glass. From the glass as a whole, and its structure composed of polyhedral inner skeleton is continuous, homogeneous and disordered. That can mean of each phase gay and glass properties change with composition of continuity. Silicate glass, all kinds of oxide is divided into three types: one kind is like silicon oxygen tetrahedron can produce glass and in the structure formed in the network, referred to as the glass body is generated; Another class of alkali metal oxide, whether individually or jointly to exist can produce glass, can only be embedded in glass structure in the network, called the network outside the body; There is a kind of both can enter the structure of the network can also be used in a network, known as intermediates. Fracture structure network depends on the number of cationic, ionic radius, ion energy, polarization ability, etc. , and thus lead to changes in glass properties. The impact of these properties to glass, also have relationship to bone porcelain glaze. The classification of bone porcelain glaze for general bone porcelain, bone China, many different kinds of glaze, the corresponding classification method is very much also. Traditional Chinese used in the production of bone China is mainly feldspar glaze and lime glaze two kinds big. Bone China ( Bone China) The production mainly use the fritted glaze. ( 1) According to ingredients points according to ingredients can be divided into the lead glaze, lead-free glaze, lime glaze, feldspar glaze, boron touch, lead, boron, salt glaze, etc. ( 2) According to the firing temperature points according to the sintering temperature can be divided into high temperature glaze, medium temperature and low temperature glaze. Generally called 100 under firing glaze fusible glaze, 1100 ~ 1250 ℃ firing glaze for medium temperature, high temperature above 1250 ℃ firing glaze for glaze. ( 3) According to the bone China appearance feature points according to the appearance feature can be divided into transparent glaze, opacified glaze, color glaze, crystalline glaze matt glaze, glaze, glaze, glaze cracks, etc. ( 4) According to the preparation methods of the bone porcelain glaze points according to the preparation methods of the glaze can be divided into raw glaze, the fritted glaze glaze, molten salt axis, soil, etc. ( 5) According to the type of bone porcelain body points according to body type can be divided into the porcelain glaze, ceramic glaze, stoneware glaze, etc. Bone China in a soft and hard enamel and enamel. ( 6) According to electrical points according to performance can be divided into ordinary glaze and glaze semiconductor. — Tangshan bone China tableware to be continued. 。 。 。 。 。
