Embodiment 1

[0027] A kind of preparation method of translucent ceramic comprises the steps:

[0028] 1) Crushing, sorting, grinding waste jade, waste glass, burnt talc, feldspar and kaolin in the required raw materials, passing through a 100-mesh sieve, drying, and then weighing each raw material according to the required ratio and mixing , to obtain raw material powder after stirring evenly;

[0029] 2) Weigh the sodium carboxymethyl cellulose according to the required ratio, add water and stir quickly, dissolve the sodium carboxymethyl cellulose in water completely and then add it to the raw material powder mixed uniformly in step 1), and use a fast grinder to Add water and wet mill for 30 minutes; then add glycerin and mix evenly to obtain a mixture;

[0030] 3) Pass the mixture in step 2) through sieves of 120 mesh, 160 mesh, and 200 mesh respectively, and use a 1T-type iron remover to remove iron, and then use a gypsum mold to dehydrate the raw materials after iron removal by the ir...

Embodiment 2

[0034] 1) Crushing, sorting, grinding waste jade, waste glass, burnt talc, feldspar and kaolin in the required raw materials, passing through a 100-mesh sieve, drying, and then weighing each raw material according to the required ratio and mixing , to obtain raw material powder after stirring evenly;

[0035] 2) Weigh the sodium carboxymethyl cellulose according to the required ratio, add water and stir quickly, dissolve the sodium carboxymethyl cellulose in water completely and then add it to the raw material powder mixed uniformly in step 1), and use a fast grinder to Add water and wet mill for 40 minutes; then add glycerin and mix evenly to obtain a mixture;

[0036] 3) Pass the mixture in step 2) through sieves of 120 mesh, 160 mesh, and 200 mesh respectively, and use a 1T-type iron remover to remove iron, and then use a gypsum mold to dehydrate the raw materials after iron removal by the iron remover to a moisture content of 20 %, moisturizing stale for 4 days, get mud; ...

Embodiment 3

[0040] 1) Crushing, sorting, grinding waste jade, waste glass, burnt talc, feldspar and kaolin in the required raw materials, passing through a 100-mesh sieve, drying, and then weighing each raw material according to the required ratio and mixing , to obtain raw material powder after stirring evenly;

[0041]2) Weigh the sodium carboxymethyl cellulose according to the required ratio, add water and stir quickly, dissolve the sodium carboxymethyl cellulose in water completely and then add it to the raw material powder mixed uniformly in step 1), and use a fast grinder to Add water and wet mill for 60 minutes; then add glycerin and mix evenly to obtain a mixture;

Abstract

The invention provides semitransparent ceramic and a production method thereof. The semitransparent ceramic comprises, by weight, 22-100 parts of waste jade material, 0-40 parts of waste glass, 0-2 parts of calcined talcum, 0-30 parts of feldspar, 0-6 parts of kaolin, 0.2-0.8 part of sodium carboxymethyl cellulose and 0-0.7 part of glycerin. The production method includes: processing and evenly mixing the needed raw materials to obtain a mud material; repeatedly kneading the mud material until even mixing is achieved, then wrapping the mud material with wet cloth for standby, sufficiently drying bases according to the different required shapes of the bases, and performing secondary calcining under 1130 DEG C, 1160 DEG C or 1200 DEG C. The semitransparent ceramic and the production method have the advantages that the waste jade material is used as the main raw material, the glass-phase content in the bases is increased by the waste glass to increase the transparency of the bases, and the production method is simple in process, easy to operate, low in raw material cost, high in practicality and capable of achieving industrial production.

Description

technical field [0001] The invention belongs to the field of ceramic processing, in particular to a translucent ceramic prepared by using waste jade materials and a preparation method thereof. Background technique [0002] Transparent ceramics originated in the 1950s. After decades of research and development, from sintering densification to controlling the growth of grains, from different crystal systems and doping options, to control transparent ceramics with various functions. [0003] The light transmittance of ceramics is a comprehensive index, and the intensity of transmitted light is I=I 0 (1-m) 2 e -(a+S)x , where m reflection coefficient, a absorption coefficient, S scattering coefficient, I / I 0 is the transmittance. When the light is irradiated on the porcelain body, part of the light energy is reflected by the surface, part of the light energy is absorbed and scattered by the porcelain body, and the remaining light energy is transmitted through the porcelain b...
