Abstract
The present invention relates to a reinforced ceramic and a production process thereof, particularly to a reinforced osseous ceramic and a production process thereof. The reinforced osseous ceramic comprises dragon rock washing mud, feldspar in Hunan province, clay soil in the Guizhou province, alpha-alumina powder and synthetic osseous powder. The production process for the reinforced osseous ceramic comprises the following steps: preparing blank materials, preparing a blank, preparing glaze, and carrying out blank vitrification. The reinforced osseous ceramic overcomes the defects that the two-step firing process (high-temperature biscuit firing and low-temperature glaze firing) need to be adopted because the supporting point of the traditional osseous ceramic is lowered under the condition of the high-temperature load so as to cause the softening deformation. The production process has the advantages that the one-step firing process is realized, the energy saving effect is obvious, and the folding strength of the reinforced osseous ceramic is improved. Because the synthetic osseous powder is used as a fluxing agent of the blank material, the transmittance of the reinforced osseous ceramic is superior to that of the osseous ceramics in other types.
Description
Technical field
The present invention relates to a kind of reinforcement porcelain and production technique thereof, relate in particular to a kind of reinforced osseous porcelain and production technique thereof.
Background technology
At present, the sclerotin porcelain good transmittance on the market, but folding strength is lower, and because its blank reduces at high temperature load situation lower support point, easy softening transform and must employing double-firing process (i.e. a high temperature biscuiting, a low temperature glaze firing), power consumption is big, the cost height; And high silicon is strengthened porcelain, high-aluminum reinforced porcelain, magnesium-intensified ceramic etc., its folding strength height, but light transmission is relatively poor.
Summary of the invention
The objective of the invention is to overcome the deficiency on the prior art, a kind of reinforced osseous porcelain and production technique thereof are provided, the product of producing had both had sclerotin porcelain good light transmittance, the folding strength that has the High-Temperature Strengthening porcelain again, realize once-firing, help energy efficient, reduce production costs, expand export and earn foreign exchange.
The present invention is achieved through the following technical solutions:

Advantage of the present invention and beneficial effect are:
1, owing in blank, introduces corundum material (alpha-aluminium oxide powder), make it in high-temperature calcination, to strengthen point of suppon, overcoming the conventional bone porcelain reduces at high temperature load situation lower support point, easily causing softening transform and must adopt twice firing (is the high temperature biscuiting, low temperature glaze firing) shortcoming, realized once-firing, energy-saving effect is remarkable.The main framing effect is played in being added in of alpha-aluminium oxide powder in the base substrate, thereby generates more mullite crystal in high-temperature liquid-phase, thereby improves the folding strength of product.
2, adopt synthetic bone meal (major ingredient is a tricalcium phosphate) as the fusing assistant of blank, can make the transparence of product obviously be better than the reinforcement porcelain of other types.
