Disclosed is a pottery greenware material by which a pottery having both productivity and quality can be produced with a high degree of freedom depending on an intended use thereof. The pottery greenware material includes a first greenware material and a second greenware material; both the first greenware material and the second greenware material including, as chemical species, SiO.sub.2, Al.sub.2O.sub.3, and either one or both of K.sub.2O and Na.sub.2O; and an average particle diameter (D2) of the second greenware material being smaller than an average particle diameter (D1) of the first greenware material.

A method is provided for inputting thermal energy into fluidic medium in a process or processes related to oil refining and/or petrochemical industries by at least one rotary apparatus comprising a casing with at least one inlet and at least one exit, a rotor comprising at least one row of rotor blades arranged over a circumference of a rotor hub mounted onto a rotor shaft, and a stator configured as an assembly of stationary vanes arranged at least upstream of the at least one row of rotor blades. In the method, an amount of thermal energy is imparted to a stream of fluidic medium directed along a flow path formed inside the casing between the inlet and the exit by virtue of a series of energy transformations occurring when said stream of fluidic medium passes through stationary and rotating components of said rotary apparatus, respectively. The method further comprises: integration of said at least one rotary apparatus into a heat-consuming process facility configured as a refining and/or petrochemical facility and further configured to carry out heat-consuming process or processes related to refining of oil and/or producing petrochemicals at temperatures essentially equal to or exceeding 500 degrees Celsius (° C.), and conducting an amount of input energy into the at least one rotary apparatus integrated into the heat-consuming process facility, the input energy comprises electrical energy. A rotary apparatus and related uses are further provided.

An object of the present invention is to provide a building large porcelain panel that prevents the efflorescence.

As the solutions, a building large porcelain panel according to the present invention is formed by kneading a raw material formulation containing, as a main material, a refractory aggregate, a glassy raw material, and cement, and subjecting the raw material formulation to molding and then firing, wherein the building large porcelain panel has a Na.sub.2O content of 1 mass% or less in an entire chemical-component composition of the building large porcelain panel fired. In addition, the building large porcelain panel has a Na2O content of 1% or less and containing 0.5 to 7% of BaO and 0.5 to 8% of B.sub.2O.sub.3 (12% or less of the BaO and the B.sub.2O.sub.3) at mass-based chemical component values.
