Stone is formed from 5 to 60% by weight of polymerised, low-viscosity, transparent or low-colour-resin, 20 to 90% by weight of spherical alumina trihidrate Al2O3.3H2O containing less regular particles containing, advantageously 0 to 100% by weight of a transparent or translucent substitute of alumina trihydrate, and / or with 0 to 20% or pre-prepared particulate, filled resin of a chosen colour, and / or mineral particles and less than 2% by weight of luminophor. These individual components are mixed intensely whilst extracting included gaseous parts. Extraction is carried out whilst mixing, and / or after mixing, and / or before mixing. The mixture is initiated by introducing a starter and intensely mixing it into the mixture. The mixture is poured into a mould or onto a moving endless belt. The cured synthetic stone is removed from the mould or the hardened composite is taken off the the belt. Synthetic stone can be used in products as a light carrier.

A blow-molded article having improved well-defined corners is provided.

A compound has at least three functionalities, including a first functionality (a) that is a sulfonate group or a sulfate group of the formula —(O)d—SO3M with d=0 or 1 and with M=hydrogen or a monovalent metal cation or a corresponding portion of a multivalent metal cation; a second functionality (b) that is a (meth)acryl residue; and a third functionality (c) that is a carboxylic acid function and / or a thioether group. When the compound is free of silicon, the sulfonate or sulfate group and the (meth)acryl residue are separated from each other by a hydrocarbon-containing residue having a carbon chain. The carbon chain is interrupted by S or NH, or the carbon chain contains a linking group, selected from C(O)NH, NHC(O), NR8C(O), NHC(O)O, NR8C(O)O, NHC(O)NH, C(O)NHC(O) and —C(O)S—, wherein R8 is alkyl or alkenyl or a (meth)acryl group.

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.

The invention discloses a diatom-containing ecological brick and a production method thereof. The diatom-containing ecological brick is prepared from the following raw materials in parts by weight: 20-50 parts of diatomaceous earth, 1-3 parts of composite catalyst, 1-3 parts of nano-silver antibacterial agent, 10-30 parts of lithium feldspar, 10-30 parts of albite, 10-30 parts of wollastonite, 1-5 parts of pigment, 10-26 parts of 30% sodium silicate water solution adhesive and 4-12 parts of water. The raw materials are prepared into a finished product by the processes of dry-mixing, wet-mixing, pelleting, drying, compression moulding, drying, firing, cooling, checking and the like. The product provided by the invention is made from pure inorganic materials, and does not easily mold; the diatom-containing ecological brick is laid onto a wall by a dry method during construction, thus being convenient in construction, short in period, high in efficiency and low in cost; compared with a diatom ooze-containing decoration wall material, the strength and water resistance of the diatom-containing ecological brick are remarkably improved, and the service life of the diatom-containing ecological brick is remarkably prolonged.

The invention discloses a preparation technology of black tea pearl rice. The preparation method comprises the following steps of: extracting concentrated solutions of black tea, green tea, corn stigma, poria cocos and radix puerariae respectively, and uniformly mixing the concentrated solutions with the prepared oyster mushroom slurry, tremella slurry, ramie oil and hippophae rhamnoides powder; stirring the mixture with corn powder, millet powder and polished round-grained rice powder to obtain granules; performing the puffing and extrusion processes with granulation equipment, and forming with a die to obtain golden yellow and bright black tea pearl rice the same as rice grains; and drying, finishing, sterilizing and packing to obtain a finished product.

The present invention provides a method for manufacturing a semiconductor device exhibiting improved emission efficiency by reducing strain between a p-contact layer and a transparent electrode. A transparent electrode made of IZO (zinc-doped indium oxide) is formed on the p-type contact layer by vapor deposition or sputtering. Subsequently, the p-type cladding layer and the p-type contact layer are p-type activated by indirect resistance heating, and the transparent electrode is crystallized. The heat treatment is carried out at a temperature of 700° C. under less pressure. Next, microwave heating is performed at a temperature of 100° C. to 350° C. for three minutes to thirty minutes by irradiating microwaves with a frequency of 5.8 GHz in a nitrogen atmosphere. This reduces the strain on the transparent electrode and improves the conductivity or translucency of the transparent electrode.
