Overview of Ceramic Pigment
Ceramic pigment is a generic term of the pigment used on ceramics, including the glaze, underglaze and glazes and blank coloring pigment. In the ceramic production process, these pigments to be subjected to the calcination of the different temperatures, the requirements are also different as for different purposes pigment. The underglaze pigments should undergo high temperature (1300℃) calcination, requiring high stability, but the variety is less, the earliest use is the blue and white, underglaze red, and in recent years there has been red, yellow, blue, green, black, gray, brown and so on. Glaze pigments only need to withstand a temperature of 600 ~ 800℃, and thus a wide variety of rich colors. Further, as the glaze stain also has liquid paint, such as KS, etc., is a metal with organic synthesis vulcanization RESINOIDS, coupled with an organic solvent is made. The seventies is developed under a high temperature and fast firing pigments (glaze) color sintering temperature of 1100 to 1260℃, the color burn time is 35 to 120 minutes, so the tone will be rich.
The Ceramic Glaze Stain Price Volatility
It is precisely because of the influence of market expectations, from January to June this year, the ceramic pigments market prices strongly get higher. Praseodymium oxide soared to 210,000 RMB / ton from 160,000 RMB / ton, up 600 RMB / ton zinc oxide imported zirconium up to 100 U.S. dollars / ton, the domestic zirconia rose 1,000 RMB / ton. According to the analysis of industrial insiders, copper, cobalt, nickel and other nonferrous metals in boosting international market prices are higher, as well as the shipping price rises under the influence of ceramic color glaze industry veteran, the domestic pigment price increases ranging from 15% to 30%. In addition to the prices of non-ferrous metal raw materials, starch-based raw materials have risen. In addition, as an important raw material, color glaze frit price also increased, rising as much as 20%. Ceramic color glaze industry is relatively low technical threshold, enterprise product development capabilities are poor, and it is vulnerable to the strong of international market prices of raw materials.
Chinese Ceramic Raw Material Supply and Demand
For ceramic raw materials prices, from the point of view of production and sales volume, the market growth spurt in the second half of last year, the sector is generally optimistic market expectations; followed by the point of view from the current layout of the ceramic industry, ceramic production nationwide flowering pattern is formed, the northern ceramics production capacity gradually increased and the proportion of ceramic production patterns are changed; Third, countries are increasingly stringent restrictions on the exploitation of mineral resources, northern production of raw materials, because of the high proportion of iron, titanium and other ingredients, are not suitable for the production of high-quality polished tiles.
